I use my PS3 more as a media centre than a games console. As such, I find myself using this remote more than the original controller. One of the key selling points for me is that, being a bluetooth device, this remote doesn't require line of sight with the PS3. This means I can keep the console in an enclosed cabinet and still have no problems accessing it.
I'd highly recommend this remote to anyone using their PS3 for media other than games.
