nope, that's crap. if *you* don't see a huge difference between idle processor 
and a movie playing/compile/gamin then it's your hardware that's shite. or do 
you actually think that all those patching of all the apps to not run extra 
timers was to save a minute or two?

nope, as noted above it's your hardware that sucks if that's not the case. an 
idle 13" laptop with no usb pollin devices should be takin about 10Watts. 
lowerin the screen brightness to maximum will win you a few watts as well.  
playin a full screen movie, compilin, playin a game, etc it will likely jump 
to 20Watts+. if you don't see that then your acpi setup is busted. so we're 
talkin about hours of difference (especially for people with larger batteries).

as to the rest, it's about feelings, which honestly is a shite discussion to 
have in a context of a development list. my point is "it's wrong to have a 
computer guess/lie", yours is "but it's nice!", which is a discussion no one 
can win. as i said in my last email "if we only had like, i don't know, a 
'usability team' to look at those issues!".
