I’ve done a lot of thinking about the Apple TV. For some reason it fascinates me. It’s entirely different from the other applications of software. First, it’s a shared experience rather than a direct experience like a Mac or an iOS device. Second, this shared experience means there’s necessarily an indirection of input — if a screen is big enough to be seen by everyone in the room you’re not going to be close enough to it to mess with it directly. So when the rumours went around of an iOS based Apple TV coming I became intrigued and tossed some ideas back and forth with a friend. Mostly the discussion came down to input methods — what could they do and what’d that mean for the interface? Around that same time Bluetooth 4.0 was ratified and the specification includes a low power mode. I guessed that if the Apple TV had a Bluetooth 4.0 chip then we’d see a new remote, if not we’d likely just stick with what we had.

[Interesting thoughts. Still not convinced Apple will do something, but I have no doubt they could if it made business sense.]
