This is a total rip of the Wacom Bamboo Touch that has been out forever!
The multi-touch is nice and great for web and some Adobe apps. It's really poor for gaming, even though it seems like it would be cool. Overall I found it awkward compared to a mouse and much harder to perform precision movements.
this would enable the Live Tiles desktop on windows 8 to be much more usable for those who want to.
or make browsing lare folders of pictures etc easier, even with the "classic" interface. not a replacement for a mouse, an add-on.
