I'm sure this has beek asked before, but a search brought up nothing. I'm considering buying my first Mac, and I want to get a 15" PowerBook. There's a problem though: I can't stand the layout of the UK keyboard. The Return key is way too weird looking. I've been using US keyboards my whole life and I have no intention of changing now if I don't have to. I'd like to buy a US keyboard and simply use that instead. Would this work? Can I just pull out the UK one, put in the US one and make a few software keyboard layout changes?
