Except when, you know, it doesn't. Turning off the lights is not analogous here.

Let's try to avoid the preachy warm-fuzzies and stick to the facts (now that we have them).

These aren't desktop machines that consume huge amounts of power when they're on and idle, these are mobile computers that consume practically nothing when they're idle. A tablet can run for 30 days when it's completely idle.

Any argument claiming that a tablet consumes the same amount of power when it's on with the screen off and the CPU idle, as when it's on with the screen on and the CPU active displaying a banner is completely and entirely bogus. The first situation can get up to 30 days of battery life, the second might get you 7 hours.

So, yes, turning the screen and CPU on to display a banner uses a non-trivial amount of energy. Honestly, I find it somewhat disturbing that a UI designer doesn't seem to realize exactly how little power the tablets use at idle (or maybe you're just overlooking it to boost your argument). :\
