I decided to keep my 1.5ghz 12"pb, opting to buy a new PC or iMac (once they upgrade them with a better vid card for windows gaming ) instead of a mbp. But one they intel transition is complete, will I still be able to buy batteries for my pb? I plan on keeping it for probably another 2 years (until my apple care runs out) and in that time i imagine the battery I have in it will not be able to fully charge anymore. Will they still sell batteries for my pb in a few years? I am thinking I should buy another battery for it in a few months to have as a backup battery. any thoughts?
