A new kind of electronic-book reader has been making its way into the market. Based on the most recent electronic-paper technology from E Ink, it boasts an extremely fast page-flip speed and several unique features. But how does it compare to some of the other new devices on the market? Find out as TFOT takes a close look at the current and future state of electronic-paper technology.
Recently the French company Bookeen introduced its own electronic-book reader to the market called Cybook Gen3, also based on E Ink’s technology. This review will assess the Cybook’s stronger and weaker points and how it compares to other devices on the market.
TFOT has already covered the history and basic technology behind electronic paper; however, it is worth expanding a little bit more on specific technology behind the Cybook.
The Cybook Gen3 uses E Ink’s Vizplex technology. This relatively new e-paper technology improves some basic features of the company’s original e-paper technology used in previous models, such as Sony’s original PRS-500 and the iRex iLiad. Among the improvements of this new generation, E Ink mentions:
Simply put, Vizplex results in devices with almost double the page-turning speed, slightly better brightness, and the option to double the number of gray levels (to date, no device has been released with Vizplex and eight levels of gray scale. Something E Ink does not officially publish is the fact that Vizplex has actually reduced contrast to 7:1, down from 8:1 in the original e-paper version. Both these numbers are ridiculously low when measured against modern LCD panels (typically, up to 3000:1 or more). But as we will see later in our interview with Bookeen, they are actually getting close to the contrast level of printed material.
Before we continue with the review, we’d like to explain an important point regarding the Cybook. When we first received the unit, we initially downloaded a bunch of heavy PDF documents onto an SD card and tried reading them on the device. The results were very disappointing. Although in some cases it was possible to read the text in landscape mode, in many cases the text on the PDF was way too small to be considered readable. In the worst case, large, complex PDF documents appeared blank, and with several documents our device crashed altogether. We asked Bookeen about this behavior, and their answer (in the interview section below) was that the Cybook was developed as a dedicated device for reading e-books. Although supported, reading PDF documents is a bonus feature. More interestingly, Bookeen claims that in order to create a true PDF-reading machine, one will have to create a device with a 10-inch to 13-inch e-ink display—something that hasn’t been done to date and will probably be very expensive, given current e-book prices.
At the end of the day, when considering the Cybook, keep in mind its purpose: if you are looking for a dedicated electronic-book-reading device, feel free to move to the next section of the review; if most of your reading is done through PDF documents, we suggest sticking with your laptop or ultra-mobile PC—or better yet, plain old paper. At least until a dedicated PDF-reading device with a large-size e-ink-based display appears on the market.
We’ve divided the interface section into two parts: hardware layout and software interface.
On the right side of Bookeen’s device, there are two plus and minus keys. These keys are used to increase and decrease the volume when playing MP3 files. It would have been nice to be able to use these keys, or an additional two, to control the font size, but this doesn’t seem possible on the current firmware version.
At the lower part of the device, you will find a rubber piece that, when removed, reveals a small charging and sync connector. Bookeen uses a mini-USB connector—a good idea, in case you lose the wire that comes with it. The Cybook is charged using a supplied USB cable. Behind the small rubber piece is a 2.5mm sound plug for listening to MP3s on the device with the supplied earphones.
Navigating with the up, down, left, and right keys is fairly simple, just keep in mind that this in not a PC or LCD screen and that it takes a bit more time for the cursor to reposition itself on the display. The black-and-white nature of the current e-ink display makes it pretty difficult to always keep track of the location of the cursor, and we found ourselves moving up and down just to understand where we were.
One of our biggest complaints about the current firmware version is that it does not include hierarchical directories. Everything is either on a device-created e-book, music, image, or font directory, with no subdirectories. If you add 200 books, you will have to scroll and scroll and scroll until you find what you are looking for—unlike the Kindle, the Cybook does not have a keyboard or any real search option.
When starting to read, the Cybook creates a bar at the bottom of the screen showing where you are in the book. This is a nice touch, but it would be nice if Bookeen added page numbers (even artificially created numbers, if no such information exists on the file) to make it easier to figure out where you are. You can choose to show only certain types of files—hiding images, e-books, or music files, for example—but after the device restarts, it doesn’t seem to save these selections. It also doesn’t seem to return to your last page read after turning it off and back on—a function that many users have asked for. (A good compromise would have been a dedicated hardware button for returning to the last page read, but the Cybook is short on hardware buttons at this stage).
Pressing the function key opens a menu that includes several options: back and forward, start reading (which takes you to the first real page of a book), “go to” (which let you go to either the first or last page, the table of contents, or a specific page number using an on-screen number dial). Other functions include bookmarks, which allow you to add and move between existing bookmarks in a book, as well as a layout function that lets you add and remove the header and progress bar, justify the text, or bold the text for easier reading. Additionally, there are font-family and font-size submenus (the device comes with three fonts, but it is possible to add new ones).
One thing we thought was missing was a quick way to close a menu without actually changing anything. We eventually found that pressing the left or right buttons performs this task, but we feel Bookeen could have include a dedicated cancel button, and maybe cancel/return option in each menu.
Before we talk about performance, let’s consider the Cybook Gen3’s official specifications first:
Display—6-inch E Ink Vizplex screen, with 166 DPI, B&W, and four gray scale
Processor—Samsung 200MHz (S3C2410 ARM920T)
Size—4.7”x7.4”x0.3” (118x188x8.5 mm)
Weight—6.13 ounces (174 g), including battery
Battery—1000 mAh Li-polymer battery (8,000 screen refresh)
Input/output—SD card (no SDHC support), mini-USB 2.0, 2.5mm earphone plug
Memory—8MB ROM, 16MB RAM, 64MB internal Flash
Supported formats—e-book (Mobipocket PRC, PalmDoc, HTML, TXT, PDF), image (JPG, GIF, PNG), sound (MP3), fonts (TTF)
The Cybook is a fairly responsive device most of time, which was one of our biggest concerns, knowing the limitations of current electronic-paper technology. Although it’s still faster to flip a page of a regular paper book, the device isn’t significantly slower. Although we had only limited experience with the Sony PRS-505, the Cybook was noticeably faster and more responsive.
As is the case with all e-paper-based devices, the display does not emit light of its own—unlike other widespread technologies, including CRT, LCD, Plasma, and even OLED; in this respect, it is very similar to real paper. However, as mentioned, the contrast level of the Cybook and other e-readers still falls short. To be specific, the white background appears more gray than white. We took a closer look with a 6X magnifying glass and, in doing so, revealed part of the reason why the e-ink display has such a low contrast, and why the background looks the way it does: as you can see from the image we took, the Cybook display has many tiny, dark “pixels” that, when viewed from a typical reading distance, make the screen appear gray. These pixels are actually the microcapsules that create text on the device.
According to E Ink: "Each microcapsule contains positively charged white particles and negatively charged black particles suspended in a clear fluid. When a negative electric field is applied, the white particles move to the top of the microcapsule where they become visible to the user. This makes the surface appear white at that spot. At the same time, an opposite electric field pulls the black particles to the bottom of the microcapsules where they are hidden. By reversing this process, the black particles appear at the top of the capsule, which now makes the surface appear dark at that spot."
Low contras makes reading more stressful on the eyes. However, the Cybook was still more comfortable to read than any LCD due to the lack of backlight or flicker. On the other hand, we do not recommend using the Cybook, or any other e-book, in low light. In the future, Bookeen and other manufacturers could consider creating a dedicated portable LED light that can be attached to the device for reading in the dark.
One advantage of the Cybook, and potentially any e-paper-based device, is its amazing battery life. With our moderate use, we never drove the battery below 70 percent. We can’t really confirm the 8,000-page-flip battery life stated by Bookeen, but even if the real number is half that, it means you could get several weeks of reading out of the 1000 mAh battery without the need to recharge—surely something most of us are not used to, based on our experience with most existing electronic gadgets (this may change when powerful fuel-cell batteries start appearing on the market).
An additional Cybook feature we really enjoyed was the MP3 player. Yes, there are better MP3 players on almost any gadget you can imagine today, including cell phones, PDAs, and of course dedicated players, but it’s a great addition to the reader, and you can easily play music while you read. It would be nice to see Bookeen expand this feature, which is currently a basic play and stop. Bookeen could add a playlist feature and, maybe in future versions, dedicated buttons for playing music. Another thing Bookeen should consider is moving to a 3.5mm connector, though this may not be possible due to the thin footprint of the Cybook; alternatively, they should find a way to allow the connection of a 3.5mm converter, which cannot be attached at present due to a small, upper plastic part. Using the Cybook as a music or podcast player brings up the question of the battery: from our experience, playing music drains a battery considerably faster than normal; however, we still got a respectable five hours of play time (though Bookeen’s official number is three hours). The Cybook also lacks SDHC support. E-books do not require much space, and dozens could easily fit on a 2GB SD; music, on the other hand, could benefit from the capacity boost of the SDHC standard.
The first e-book format we tested was Mobipocket, which reads files ending with .prc or .mobi. Mobipocket is a French company that was purchased in 2005 by Amazon. The company created free software, called Mobipocket Reader Desktop, that helps the user manage and synchronize content with a portable device (in our case, the Cybook).
In our experience, the Mobipocket Reader actually worked well, and it’s a very simple, efficient piece of software. The Mobipocket Reader lets you add books and RSS feeds, as well as buy e-books from a variety of online stores. To our surprise, we were able to find quite a few e-books, and though we are still far away at this stage from a time in which all new books have an electronic version, there is plenty of reading material to suit almost anybody. Prices are mostly fair—you can easily find books for less than 50 cents (we found several titles by Asimov at this price range), and other books cost anywhere from several dollars to several hundred dollars, in rare cases.
We went on to test TXT and PDF formats downloaded from the well-known Project Gutenberg Literary Archive, which worked very well apart from the lack of page numbers that made reading a bit difficult. We tried HTML files and had some issues, but it could have easily been our fault.
To sum things up on the format side, we were very pleased with Bookeen’s choice to go with the Mobipocket format and software. It could even be argued that the ability to convert PDF and other types of files into .prc or .mobi formats makes the somewhat problematic Cybook support for PDF files less important, as you can fairly easily convert the document into a readable format. As we have seen, conversion is never perfect, and, frankly, we don’t see a reason why Bookeen should not provide perfect PDF support for its device out of the box.
One of our favorite features of the Cybook has nothing to do with e-books at all. Using the Mobipocket Reader software, we were able to integrate a fairly good and especially useful RSS support for the device. People who otherwise would have no interest in the Cybook could buy it simply because they want a comfortable device with a good screen to read their favorite feeds on their way to work. Although you can read RSS on most cell phones and any laptop, these devices have their limitations: cell phones tend to have a very small display, and laptops can be too big and cumbersome, even some of the new thin and light ones. They both also rely on LCD technology, which is inferior in many respects to e-paper when it comes to reading long texts. Of course, not everything is perfect and without wireless capabilities, the Cybook can only sync when connected to a PC with Mobipocket Reader software. The Kindle includes a free high-speed data network in the United States, but the Cybook requires paying for RSS-feed subscriptions.
As for the experience of reading feeds on the Cybook, we can say that it was fairly acceptable, even with the current firmware. The big drawback, of course, was the lack of folders and subfolders, so our 100-plus feeds got mixed in with all the other content on the device. We recommend that Bookeen create special software for RSS that would increase its capabilities, including different viewing options that show RSS feeds in a list or detailed format, similar to the dedicated music folder. Also helpful would be a feature for each feed that includes a list of news items and lets the user read specific items instead of scrolling endlessly through dozens of pages and irrelevant user comments.
Bottom line: if Bookeen indeed improves RSS capabilities of the Cybook, it could prove to be a killer feature for many users who are interested in catching up on their favorite feeds on the go.
On the positive side, we can definitely say that, for the most part, the Cybook is fairly quick and responsive. It has a readable display, good battery life, good RSS support, and as a dedicated e-book reader it usually does its job very well.
On the downside, it is hard to use the device without considering how much better it could have been given slightly improved hardware and more robust firmware.
In terms of hardware, a better page-flip mechanism is a must, and more—and bigger—hardware buttons (user reconfigurable, if possible) are also highly recommended. Adding a keyboard, like that on the Kindle, would also be a good idea, though it would increase the device’s size. Another possibility might be to create a slider with a keyboard that opens only when you need it, keeping the device small while increasing its functionality.
Adding some sort of wireless capability—3G or Wi-Fi—would also be very welcome, it would definitely reduce the battery life and increase the cost of the device.
To be honest, the current firmware feels like it was rushed to the market too soon, and it handles more like a beta version than an actual commercial version. The device does seem to have a lot of potential, as long as Bookeen continues to release updated firmware versions to fix many of the current issue and adds several features to make the device a highly capable e-book reader.
None of the e-books that we are familiar with and are currently on the market are perfect. Each has advantages and disadvantages in cost, performance, feature support, or other respects. As of early 2008, e-paper technology in general and e-book readers in particular are taking their first commercial steps. We see tremendous potential in this technology that could very well change our lives in the next few years. Although our experience with the Cybook proved that technology can be useful even today, we still think the true life-changing nature of e-paper technology has yet to reveal itself.
For those who like the gist:
TFOT recently interviewed Michael Dahan, co-founder of Bookeen, to learn more about the company and its future plans.
Q: When and how was Bookeen formed?
Now it seems obvious to everyone why Cytale has failed, but if you observe the current market, you can see that some of the actors are still going through the same story: closed model, weak catalog, high-priced device. At the end of Cytale, Laurent and I decided to offer a second chance to the Cybook, and we launched Bookeen. Our first step was to open the device to many digital formats; by doing so, we immediately increased the number of digital documents that can be read on the Cybook. We signed a partnership with Mobipocket for DRM content, and also with Gowerpoint, with their excellent MicroBook reader for HTML, TXT, and RTF formats. We also worked on a PDF reader. Thus, the Cybook was the first e-book reading device to natively support so many formats. In the end, it is able to read a DRM catalogue of 50,000 titles and millions of free documents available through the web or generated by the customer. In 2005, we began working with a Taiwanese device (TFT screen, 750g, USB host, and so forth) aimed at professionals, with a high $800 price. In 2007, we spent the whole year developing a new device in partnership with PVI. This device, the Cybook Gen3, is using e-paper technology; like its predecessors, it can read many open formats and supports the Mobipocket DRM. We have clearly designed this product for the consumer market, with a paperback size and a very simple interface. The device fits in a jacket pocket or a woman handbag and benefits from the e-ink capability, offering a long battery lifetime. Since October 2007, we have run out of stock four times. Our customers and the press really like the device, especially its simplicity and its very intuitive interface.
Q: The current firmware has some bugs and is missing a number of important features, including folder and subfolder support. When should we expect the next firmware version, and what fixes and improvements will you integrate into it?
Q: What lessons did you learn from Cybook user feedback so far, and how does it influence your work on the current device and future devices?
Q: The contrast level of the Cybook is 7:1. How would you compare it to a standard LCD (which has a contrast level of 1000–3000:1) and to printed paper, and, in your opinion, how high could E Ink’s technology go in the future?
Q: So how do you compare the Cybook to other devices in terms of readability?
Q: Are you thinking about adding an LED light either inside a future version of the Cybook or as an add-on for reading in the dark?
Q: Is there a danger of burn-in leaving the same image on the screen for a long time?
Q: What is the life expectancy of the display, and does it degrade over time?
Q: Are you planning future devices with wireless capabilities?
Q: Are you planning support for additional formats, in particular DOC files (without using the Mobipocket conversion software)?
Q: Are you currently considering dedicated e-paper-based devices for other applications, such as PDFs, Microsoft Word reading and editing, a dedicated RSS reader, a note taker, etc.?
Q: How do you see e-paper progressing in the next five years, and what devices will we be using at that time?

Take a look at the Irex Iliad ebook for pdf reading. I have one myself
and it works very good.
whenever i see reviews of ebook readers, people seem to forget that it
is for READING BOOKS. not listening to mp3s, not browsing the
internet. books. so many of the "cons" of this device are
irrelevant, especially when you sacrifice battery life/size for the
1) wireless? is it really that hard to plug it in, or switch out an
SD card? 5+ books will last you at least a week without needing to
sync for new content, and you can fit way more than 5 books on it. an
induction cradle might be cool though...
2) better mp3 support? it's a BOOK READER. get a $20 coby player if
you're that worried. and you will still get your 8000 pages.
3) better PDF support? the problem with PDFs is that they have a
static layout (no reflow), so you'll NEVER have a good reading
experience on a book-sized screen. other elements like font choice /
size are static as well, which means you can't resize it on the fly or
choose a more readable font. therefore, (see next comment)
(continued) therefore, PDF is not a format for ebooks anyway, and
anything in PDF should have been distributed differently IF IT WAS
INTENDED as an ebook.
4) SDHC? books are SMALL. you couldn't read everything on one
regular SD card in a month. okay, maybe if you read comics, it might
be different...so bring an extra SD card or two along for those
i will concede the point about RSS feeds -- if you like to read those
a lot, then i can see how wireless might be more appealing, since
you'll be syncing it more. but it also means you'll be plugging it in
more to recharge the battery, so it might even out. switching out an
SD card shouldn't be so hard.
btw, what happened to viziplex having 8 levels of grayscale? why does
this only have 4? if viziplex supports 8, can this be upgraded via
firmware? or will we have to wait for future devices to get more than
|It is also a Vizplex screen and support 8 level of grayscale|
I actually really like the way these look/feel. I was at a convention
where a couple of people had Cybooks, and these feel really light and
look like a book. I was worried that the screen would give me a
headache (if I spend too long reading on my laptop, I do end up with a
headache). BooksOnBoard has the new edition in stock now
which is nice since these are always sold out. Do you think an
accidental damage plan is a good idea for Cybooks?
I have used my cybook for over six months now, and am very happy with
it. All the pros mentioned in the review are well supported and
attested. I also agree that this is book and that the lack of music
is irrelevant. I use the Cybook on long (14 hour) plane flights, and
have never been disappointed. However, I AM surprised at the poor
ergonomics (from a French company this is incredible. (a) The cybook
case (I bought the deluxe version) stops the user from opening the
little rubber stop to the USB port, so to charge, you must take the
case off. (2) critically, ALL THE BUTTONS ARE TOO SMALL, AND THE
MARKINGS TINY, which means they are difficult to find and use. (3)
Amazingly, the page-flip button is so bad that unless hit just right,
it either doesn't flip the page, or flips two or more at a time. (4)
WHY IS THERE NO SOFTWARE SUPPORT FOR MACOSX? A sliding keyboard would
be a great addition. Wireless, less so (among ther things, you
couldn't use it while planes are landing.
great review. but don\'t forget that you can also look up
dictionaries. another nice feature is adding more fonts. finally,
cybook is still cheaper than sony or kindle.
pdf flowing is troublesome on any device except pc of course. not a
big problem if you spend a few minutes converting from this format to
another one much suitable.
I have the Cybook Gen3 for about a year now. And it is very slick.
Unfortunately, it is also very unstable. By now, it is impossible to
read a book without having to reset the cybook multiple times. Usually
it takes 4 to 5 resets and extra charging before it will even start.
The firmware upgrade to solve these issues was promised about 6 months
Sorry, but no future for Cybook as far as I'm concerned.
Does it support popular DJVU format ?
I started with a Cybook. It failed with the first few weeks. It took
several months of complaining to get a refund. The manufacturer was
not at all cooperative.
Then I had an IRex Iliad, It too, failed wihtin g a couple of months.
Again, it took months of complaints, threats, and heavy lobbying to
get a refund.
No, I use an old 13" Mac Powerbook. It is far better than either. I
have over 900 ebooks on it as well as videos, movies, and some games.
It's a far better travel companion than either.
