I think it's pretty neat, but the only real ground-breaking thing about it is the controller-based keyboard, which I probably won't use because I prefer using a real keyboard and mouse when gaming.
If it makes it a little simpler to play a PC game on your TV, then that's cool, but it's not really that difficult to begin with, you know?
The browser stuff is nice, but again if you're connecting your PC to your TV you already have all that. The only real improvement is that's it's all-inclusive, and designed to be on a TV.
So, like, uh... I would say "it's not that big of a deal" but I don't really see people making a huge deal out of it, anyway, so .... "neat" is what it boils down to, I suppose.
