What is Apple's reasoning behind allowing RAM and HDD to be user replaceable... but not the battery? To change out RAM and the hard drive, it requires just as much effort (and by effort, I mean unscrewing a few screws and unplugging the ribbon connector) Why do they allow RAM and the HDD to be considered user- replaceable and not the battery? I just don't get it... And if I am beyond warranty date, since my MBP is no longer covered, should I just do it myself? Are the replacement batteries easy to find online? (I have NO worries actually changing out the battery myself, what I am more worried about is the quality of aftermarket batteries - I don't want anything with sub-par battery life, and/or something that will blow up in my MBP!) I don't need to replace the battery yet... but while I was already inside the case changing out RAM I just noticed how simple it would be to change the battery on my own. When the time comes... should I fork out 139 to have them do it? (My only concern is I don't want to ship the computer away or be without it for several days) or should I just order a battery from a hopefully reputable source online and do it myself?? What would you do??
