Most consumer electronics in this category don't really power down,
even if you press the physical "power off" button. A tiny bit of the
system is still running to do miscellaneous stuff. ARM9 processors
like the one in the OpenMoko have a sleep mode that freezes the system
state, but it's otherwise "on".
I have always wondered about the real reason behind asking people to
turn off phones during take off and landing. Recently I heard that
it's actually only one of the cases that matters, I think it was
landing. Once I forgot that I had dropped my phone in my backpack even
before leaving out for the airport and I realised this only when I
arrived at my final destination. I wondered how often that kind of
thing happens to people all over the world.

The first airlines already published studies, that they see no problems
with cellphones.
I don't think there will be any case where a cellphone could in any way
disturb plane electronics.
Only a matter of time till they are allowed on every plane (even it's
pretty useless without in-plane coverage).
