I've got to be honest. While I was traveling the far-east in September I saw a number of markets there selling Mac products for very good price.
I was quite tempted as they are much cheaper than original Mac software, but in the past, I bought windows vista from Bangkok, and took it back to the UK, installed it and everyting was working fine until it installed automatic update which stated that I had a corrupt version. And I couldn't use it again!
