Hi, My wife is using a 2008 13" macbook (2.4 ghz, 3 GB, 250)- easy use- on-line, e mail, writing, some video storage, no editing. no gaming). My son's netbook went down this week. I am going to help him get a new laptop for school. how much improvement is there in a new macbook (13", 4 gb, 500)? I'm deciding if I want to give him the old mac,and get a new one for my wife.
