PS3 BD BT Remote
Once upon a time I've made XBMC based HTPC... And as any proper HTPC mine should also have a remote control.
Since my TV is Sony, the choice was obvious - Sony PS3 BD BT Remote - both remotes are almost the same which makes HTPC looks aesthetic.
Then however I've realised that despite being recognized as a generic HID keyboard, keys mapped to buttons aren't seen by Xorg (XInput to be precise). Second issue i found was related to battery power. Don't know how PS3 is properly handling it but I solved the problem by suspending the HID via explicit teardown of BT link.
