i know its early but im going for the switch at christmas. this will be my first mac apart from the ones im using at school, so the first one i will actualy own. and am wondering wether i should get a refurb macbook unibody or a macbook white with some upgrades and if so which updates. (btw stock hd is now 160gb)i have a budget between £700-£800. i will be doing lots of work in pixelmator, xcode and imovie as im taking a diploma in creative and media(yr10). thanks in advance.
