This is how we got into this mess to start with. The mess I'm talking about
is why we have things like KDE that take up 250 Megs of ram just to run.
It's only 15 minutes so why worry about it is the same as saying it's only
to take up another 20 Megs of ram so why worry about it? The next thing we
know we're recommending that you have 1 Gig of ram to run XFCE 5 the new
desktop. Same goes for cpu and battery usage. If we can do the same using
why don't we do it? Yes I'm volunteering any time I can while taking into

It's not subjective, it's the result of spending the last 2 years trying to
my laptop to last as long as Windows does out of the box. I've got longrun,
I've tweaked the power management, I've changed the way I mount my

(that lasts 6 under Linux and just a bit over 8 on Windows).
If that actually were the case, I'd agree. You're not going to get a

The law of diminishing returns does NOT directly apply to battery power. The
of diminishing returns applies to cpu power, hard drive speed etc. but
are linear. You use what you use. If you use less you're battery will last
much longer. Yes, we don't want to go chasing every last interrupt but still
seem apparent that there is quite a lot that we can do without going crazy

The data might not be as fuzzy as you might think. It's not too hard to
the amount of juice being used during different activities.
Who's this 'we', by the way? Are you volunteering your time? ^_^
