I can’t see carrying one of these for use with a phone/tablet (at least not with this version’s chunkiness) but something like this with a trackpoint added would make a great companion for a home theater PC. Even better if it had multi-pairing so it could switch between a PC, console, streaming box, etc.

Currently am using a Lenovo ThinkPad Keyboard II for this purpose which is pretty good (dual RF/BT modes let me switch between devices, trackpoint is better than the chintzy integrated trackpads in most couch-keyboards), but something that takes up less coffee table space and is more like a remote would be even better.
