There should be a power button on each device screen, certainly, but the hard buttons should ALL be configurable. I agree about having a power on-off be separate buttons, some components (Harmon-Kardon) use a separate command for on and off.

This remote is ALMOST perfect. If they had 2-4 more hard buttons, for example F1-F4, is would be TOTALLY perfect. Of course I'm waiting for the software to improve and hopefully it will with time.
