I just got this yesterday to pair with my fireTV. Not bluetooth, but IR (with learning) and wireless keyboard/air mouse (via tiny usb dongle). I haven't really had a chance to use it much, but it seems to work decently. I'm having issues with some buttons not doing anything (home, FF, rev) but I think I can remap them via a file on the Android system.

However, I also have a flirc for my main HTPC (custom-built Windows rig) and that's been awesome, since I can use my universal remote to control the PC as well, making it a true all-in-one. If you need to map a keyboard combination, you can do that, and with a program like Auto Hotkey or the linux equivalent you can create custom macros to do basically anything you need.
