I do want to wait until MacWorld 2009 to see if a new iMac is released. However I often look on eBay for new iMacs that have low prices, and I have been tempted to buy a few of them because the price seemed so good. If I buy an iMac from ebay, can I still buy AppleCare, and will it work even though I'm not the original buyer? This may be a dumb question but I'm just double checking. Thanks
