I’m not certain what the future of Google TV, but there is a new keyboard for that.
The EFO Google TV keyboard is one of the smallest Keyboard remote, and it looks like it is pocket-sized.
My Source says that there is a touchpad that can work both horizontally and vertically.
You should be able to get RF versions and Bluetooth versions for $65 and $75. There is a demo video on my Source link if you want to see the tiny keyboard remote.
