I just recieved my 17"Powerbook. This thing is amazing!!!!!!...i did it, i switched, and it feels great! I just have a question: When I calaborate the battery, can I put it in sleep mode? Also, when I take it places, do I shut it down so it doesnt drain the battery, or do I put it to sleep? Thanks!!!!!! Oh yeah, I will use this thread to post any more questions I have(others feel free to do so too).
