Hi I want to get my wife a new macbook pro for her birthday. Here old one is getting pretty dated. I was hoping the new ones would be out by now and if it was for me I would wait ( I always want the latest and greatest). She just ones something that works and will last about 4 years. I tempted to wait but that messes up the whole birthday thing and I am too cheap to buy two gifts. So how are the current macbook pros, and will not new ones be that much different?
