Hi everyone im new to the forums and have been waiting to purchase a mbp for quite sometime. im one of those waiting for the update. anyways i was just curious i read a lot of posts talking about battery life and cycles and percentage drops of the mbp and was wondering what it all means... to a more specific question : if i buy a mbp how long should i expect the battery to last before i need a new one (lets say i would need at least 2 30-3 00 hours of battery life. to extend its life is it worth just taking the battery out and just leaving it plugged into the wall ? so far from what ive seen on the forums, the battery doesnt seem to last long . im a pc user and have been all my life so im used to battery life under 2 hours lol so i have a feeling i wont b too disappointed.
