How does Apple Care work exactly? It sounds like most people buy and register Apple Care shortly before their 1 year warrantee expires, which then gives them 3 years of cover after the first year? Or if you buy Apple Care with a new Mac, does the 3 years cover start after the warrantee ends anyway? If not, it sounds like you're getting 1 year less cover? Also, does anyone have any experience with Apple care, in terms of repairs? Are all repairs free? I've heard of people having to wait up to 6 weeks for their iMacs to be repaired, can it really take this long?
