I liked Apple Care until my wife's 13 month old Macbook was sent in to replace the top part of the case due to cracking, and they refused it because of 'significant liquid damage'. Mind you the Macbook was NEVER subjected to any kind of water/liquid/moisture. It worked perfect from the day she opened it, and still continues to work perfect. To me 'significant liquid damage' would be the laptop no longer works due to corrosion.
They canceled my Apple Care and sent it back to me in worse condition then when I sent it off, like the screen pulled completely apart, and not put back together, heavy damage to the top case, to cause worse cracking.
