Aaah!! I can't wait!! My first ever mac, a MBP arrives tomorrow...in about 15 hours' time!!! Tonight will be pretty sleepless!! I'm even getting off work early so I can come home and play!!! And a question...I've read all about battery calibration and stuff, and I'm wondering, seeing how more than 90% of the time my MBP will be plugged in to the power outlet, is it really necessary to calibrate the battery? And will it damage the battery if, say, over a 9 month period the laptop is plugged in the whole time? Apple describes the battery in a 'resting state' when the power is plugged in, so does that mean that the battery is bypassed?
