The machine runs both windows 7 and Android 2.2 and we've also seen it run Windows 7. The chap was playing with it using the Stylus but fingers will do just fine.
The prices we've heard around were at about $500 for the tablet but if you buy it with the keyboard it can sky rocket to over a $1000.
The device looks decent for a 10.1 inch tablet, but of course it is nothing spectacular.
This is how it looks.
