I can't argue with it being better to get things turned off, by whatever means, rather than left on, and clearly there are situations where a remote is anything-but a lazy option.
"
the answer is have the controlled device decide whether or not to turn itself on and off under the control of a set of rules proscribed by the owner."
My sky plus box goes to standby at 1am, or somesuch. I am particularly aware of this when I wake up at 2am on the sofa

I think they should program it to go into standby after, say, 1 hours running with no signals from Remote etc. At 1am it springs up a "going into standby in X minutes" warning, so the "one hour and then standby" thingie could have a similar message - I would only have to press any button on the remote to tell it to stay running.
Notwithstanding which I believe the power usage of Sky-plus on standby is not good
