I'm thinking of buying a new iMac. I can hopefully get one via a friend who's in New York for a few days. The new 20-inch iMac costs £600 ($1,200) in the US, about 33% less than the UK. With the money I save I can look at upgrading some of the components, possibly even go for the 24-inch version (as I read that the 20-inch version has a number of concerns including whether or not it's a 24-bit screen). I'd need a new power cable with a 3-pin plug (there aren't any other power issues are there?) The warranty wouldn't be valid would it? (isn't it only valid in the country in which it was purchased?) I read a thread mentioning Apple Care being worldwide- could I get this in the US for use in the UK in place of the warranty? Do I need to pay tax? If so, where and how much? Has anyone bought a Mac from the US to use in the UK? What was your experience? Are there any good websites to look at for any of the above? Am I missing something obvious that should make me abort this idea???
