I'm watching the live stream in bits and pieces. What is the "input device", exactly? A wireless mouse? That's gonna be a real pain to use.
No more fights for the controller. :)
So, a really nice Sony HDTV + Logitech Harmony + Internet... yeah, i'd love that!
I'll rephrase the question: what input device am I supposed to hand to my mother-in-law? A wireless mouse? A gyro-pointer? A mega-keyboard with a teensy little trackpad on it? And she's supposed to focus this little 32x32 cursor on the correct place on the screen?
Seriously, this is a clear example where Apple thinks things out a little better. We're now heading into an indefinite period of "OMG GOOGLE TV PWNS APPLE TV"...but Apple at least took the time to think out their answer before presenting it.
