What remote control or pointer for computers on TVs?

I'm interested in what remotes people use with computers hooked up to TVs. Mouse on the couch? Keyboard on coffee table? Wireless or not? Remote pointer like the Loop pointer or Bluetooth only? Are you happy with what you have?

Full disclosure - I do consulting for Hillcrest labs so I have more than idle interest. Seems like people with computers on their TVs (PC or Mac) have different remotes or pointers depending on their top applications, like whether you use Hulu the most or Media Center or something else.

Thanks.
