Ignorant Pom:
I usually say that the television remote provided does me just fine and then get yelled at by enthusiasts.
If you only use one remote then there's no real point in getting this. Especially if it's a decent remote.
My Harmony, at the press of a button, turns on my TV and switches it to HDMI, turns on my reciever and switches it to Digital In and then turns on my PS3.
Without it, I have to use two remotes and the controller. And then hit the one source button on the TV remote about three to switch through to HDMI as well as open the cabinet to see the receiver so I can switch it to the right input.
