Hi, Looking for some advice. I am buying a 13" MBA on the weekend and this will be my first Mac having used PCs for the last however many years. Just looking for tips and useful Apps that would help me out make the adjustment. I will only be using the MBA for generic web surfing, emails, word processing, basic photo/video editing, Itunes etc. I have an Iphone 3gs that i have had for a while so am ok with IOS. Cheers in advance.
