BGR is reporting that as of October 28, 2010 all AppleCare Protection Plans now have a 30-day window within which they are transferable to new products. The ability to transfer these plans was previously available only on AppleCare for the iPhone.
Apple hasn’t formally announced this change to the public as far as I know, but it appears that this rule will apply to purchases within the same product family. For example, if you purchase a MacBook Pro with AppleCare and then change to a MacBook Air within 30-days the theory is that you would simply transfer the AppleCare to the MacBook Air.
