I'm a Linux and PC user and I'm probably looking to purchase a mac in the not too distant future, as I need to know how to be able to teach people to use every type of OS. I have heard good things about Psystar sadly they're not in the UK at the moment, and have files for bankruptcy to try and delay the Apple court case against them. Although there is also a German outfit that are doing the same thing I'm not so sue about them.
