Intel has previously announced the development of Moblin OS, while Nokia has focused on its own Maemo OS. A few months ago, at the Mobile World Congress in Barcelona, they have announced that collaborative effort was made in order to create a joint OS, named MeeGo. However, they did not provide many details about its features; the only major information given was that it's going to be a tablet OS. According to an Italian site, HD Blog, the first MeeGo tablet should arrive in 2011. Although this video shows the OS in the pre-Alpha stages, it gives a pretty good idea of what we can expect from Intel and Nokia next year: multitasking, multimedia applications, integrated social network updates, and a "My Slate" panel, which displays information about running apps. Furthermore, there's an option for a 'simple UI' mode, which gets rid of all the rich, scrolling panels and replaces them with simple icons for launching and managing applications.
