The task icons at the base of the device's display suggest a UMPC of some kind, unfortunately if the interface remains built around touch it will be useless. My pinky would grab 5 icons at a time. Even a stylus would require a deft aim. As far as one can examin, everything says "Not complete". It must be a pipe dream from some over enthousiastic Apple fan.
The size of this device would be appropriate for a PDA but so would the iPhone and iPod Touch with the right software additions. UMPCs as they are today are a little too small to be easily usable with any input. Any computer's existence is dependant on it. Of course some people may have a use for a computer that requires only display and basic navigation, in these cases UMPCs shine. Most of us need a computer for data input, be it textual or graphic, and interface for those take up space; you can't draw with a thumb mouse or type rapidly with a thumb touch screen.
What we all need is a small tablet or pad the size of an iLiad, without bezel and roughly 1/4" thick so it is comfortable to draw or write on. Turn it sideways to display a tiny touch interface keyboard and leave several lines to display text on top to see what you do.(I made a typo writing comfortable and added a 't' at the end: "comfor
tablet" That would make for a great name

)
Better still make it two adjacent displays, clamshell like, to make it a micro laptop with one screen a touch keyboard used at will. Turn it sideways and the keyboard becomes an other vertical page. With today's technology and Apple savvy the possibilities are enticing...
