Its a moot point now that 15" MBP doesn't have an express card slot, I have a hypothetical question.
With an eSATA adapter (via express card slot) and an external hard drive, would it be possible to create a 'gaming module' by which Windows is installed as are games and other Windows applications. Your day-to-day Mac would be completely free of all things Windows, and then, when at home with all your gaming paraphernalia, you plug in the 'gaming module' boot into windows and start fragging some Nazis and the like.
I don't suppose using fw 800 would be appropriate given that the drive would be recognised as external and data rates would be too low?
Please criticise this to the nth degree, I want to hear why it is a completely stupid idea.
