Both models use Bluetooth 2.0 wireless communications and are based on an 800 dpi optical sensor. MoGo has a kickstand to prop it up at an angle - mimicking the feel of a traditional mouse, deep finger depressions, two (or, in the case of the X54T version, three) clickable buttons, auto-on functionality when it ejects from the card slot, and an underside on/off switch. A small touchpad on the MoGo X54T model functions as an integrated scrolling wheel replacement.
The MoGo Mouse's 90 mAh battery is recharged inside the card slot and seems to be enough for most users since the mouse has an intelligent power-saving technology that turns the mouse off if not used for several minutes. A simple click reconnects it.
The BT and X54T versions run $70 and $80, respectively. For laptops that don't include Bluetooth support, a tiny BT adapter is also available for $50. The MoGo X54T version will become available in Q2 of 2007.
