Sigh, and again people run off with the phone reference; it was a
sidebar, not the main point. The thought is not 'ooh, let's do what
phones do'; the thought is 'suspend/resume is probably what most people
really want to happen when they stop using the computer and then start
using it again'. In general what you want is for the system to 'turn on'
really fast and give you exactly the working environment you had before
you 'turned it off', yes? Well, that's what suspend/resume do.

"Isn't there a vast difference in the utility and power consumption
between the two?"

On most hardware, at the moment? Yes (well, not vast, but noticeable).
But hey, maybe if it becomes more normal to suspend rather than shut
down, this will be something that gets addressed.

"And it potentially has real implications in the world, ie. users' power
usage."

Again, you have to weigh the slight increase in power usage in
suspension versus complete power down against the big difference in
power usage between suspension and full power up. It's not just about
overnight; if you get in the habit of using suspend/resume all the time,
and you can truly rely on it to work, you'll do it a hell of a lot more
than you would a full power cycle. I suspend my system when I go to the
washroom for two minutes, because it's really easy to do it - two clicks
or one press of the system power button - and I know it'll come back up
working in a couple of seconds when I come back. I'd never do a full
power cycle in the same situation. Ditto getting up to feed the cat, do
some laundry, take out the trash, go to the store for half an hour...
