Ok, this has my attention.
Why Nvdia is the one to pull this off I don't know but I think its really smart. Of course I'd rather see a GPU agnostic version that MS or a 3rd party (Razer?) did themselves but this isn't bad. I don't really expect to buy one but the ingredients have been around to make this happen for awhile and the Wii U showed it could be done on a console - so I'm glad to see a PC/Android version that does it one better (not a dig against the Wii U, I think it's pretty underrated). If it ran RT instead of Android I might consider buying it (don't hit me!)...
