Hi Morten
It's probably worth installing Parallels and Windows 7, as there are a whole host of training and planning* aids (*like the new and - IMHO peerless - SkyDemon) out there that, sadly, are PC only.
I run Parallels on a MacBook Pro seamlessly: when you're fed-up with the PC

, you just minimise that window and pretend it's not there!
Good luck. Hope to bump into you at EGKA some time.
