I have a MacBook Pro 13" which I bought in March this year. My friend had his stolen and has offered me £800 for mine (it's in immaculate condition) and I'm debating whether to sell it for another Apple computer. I really like the look of the MacBook Air 13" as a replacement for mine.. Do you think this is a wise idea? Or touting for another Pro with the slightly better processors and bunging in an additional 4GB of RAM? My concern with the Pro is that they will do a product refresh again around March with a new design where as I think I should get another 6 months + of the Air without a refresh as they have been done most recently! Any thoughts? Should I just stick with mine?
