I am going to buy a 12 inch powerbook as soon as I can get the money together. My question is this: DO I have a whole year to buy the AppleCare warranty, or do I have to buy it at the time of purchase? If I can buy it during the first year, I'll be able to get my new toy a few months sooner. One more thing... Is there anyway to upgrade pbook graphics cards? I would love to have a 64 ddr card instead of the stock 32.
