Well, put it this way, its good that its free, because I wouldn't pay for it!
Now I know it's not an Apple Warranty, but some things that Apple covers, John Lewis doesn't. For instance, I was trying to get my fan fixed as it was making the "moo" noise. I still have an AppleCare warranty, but didn't have the time to travel up to the Store, plus JL's is a bit closer. The guy I spoke to on the phone, basically said "Is it useable? Does it work fine?" (Not literally, but it was basically what he was saying!)
The JL warranty is good, but I still prefer AppleCare! Plus, I live quite far away from both stores!
(I have re-worded my previous post!)
Sorry, I should have explained more!
But if the Mini was in stock I'd jump at the chance of getting one as a Media Center Mac!
