*** Apple can be forthcoming on this if you have a good reason for not being able to buy Apple Care before the end of the first year. It just happened to me. I was 12 days over the guarantee and still was able to get Apple Care the other day. My problem was that no shop in Paris, France had AC for iBook on stock two months before my guarantee would expire. Apple Store didn't even bother to give me a delay (would've been more than 2 months anyway) So, in case you have a problem just after the guarantee it's worth contactin Apple and ask them what they can propose.
