after waiting for months for an update to the 12" PB line, i purchased one this morning from the apple store. i'm hoping the heat issue has been solved in this revison (crossing my fingers). just a few questions: 1) is there a special way to treat the battery, to prolong battery life? i'm probably going to make the PB my main desktop machine (i have a G4 450 DP right now), so it'll be plugged in all the time, aside when i'm using it at school. should i take out the battery when plugging it in directly or does it not matter? 2) is there any accessories / things that i should consider purchasing for my new PB? i have purchased a "brain cell" by tom bihn (which is essentially a laptop hard case sleeve). and i was also thinking about the icurve as well. thanks!
