I have seen it commented that you have 1 year after purchase to acquire the Apple Care Protection Plan. Is this correct? Further, does the time frame of the plan start from the date of purchase? And I guess another question is what is considered the date of purchase: is it when the order was placed or when the shipment is made? Also, if you buy from an authorized dealer/repair facility do these facilities have their own or additional care plans that one could or should use?
