I'm not sure if this is an issue for everybody, but battery life is a serious issue with me and my laptop. This is compounded by the facts that:
I know about graphical views of battery life (i use iPulse but don't like how much CPU it uses) but I'm unsatisfied with them. They're good at showing you your current velocity, i.e. at this rate how long till your battery will be gone. However, they're really bad at telling you when you've suddenly started sucking up an unreasonable amount of power. What I'd like would be some kind of accelerometer that would tell me that (even though I have 2/3s of my battery available) I'm draining at really rapid rate.
Any tips/tricks on making sure you can really maximize battery life?
