I've been watching this discussion with increasing disappointment.
Suspend and hibernate are both hacks around the fact that power on and
power off take a long time and that our session manager doesn't save
session state.

Lots of progress is being made on system boot up time, it's improved
massively in the last few years in various distros and more cool stuff
is still to come. There are movements towards replacing the ancient PC
BIOS as well. And the next version of OSX contains "Resume" - which
saves the session between restarts.

Let's do our batteries a favour and concentrate on the real problems,
rather than creating an increasingly complex set of workarounds. The
correct use case for any electronic device is power on when using it,
power off when not.
