I'm a windows man, born and bred - the closest I've gotten to using a mac was buying an old old old machine for £50 with a 21" monitor (I threw the mac as it wouldn't even turn on) and playing about with the shiny things in PC World.
I was subcontracted to do some work for a university and although I've been paid in cash, my contracter has also been paid in Macs. Since it's free as in beer, I've been given an apple blueberry - 400mhz, 512mb ram, 10gig hd - apparently. It's not arrived yet.
So the big question is, why on earth would I want it :- ) I have no idea what macs can do... is this a good starter machine to learn with?
