In the market for a new laptop soonish, i need something for school mostly but will use it at home as well, i am a gamer so steam will be loaded on it and used when i am out of the house and bored! Considering the air because my last laptop was a 15 inch MBP and carrying it around with me everywhere i went would give me pretty bad back pain, something lighter hopefully would make this less of a problem. It's not been an issue at all with the iPad so hopeful it wont be with the air. The flip side is i want something that will last me 3 years and not feel sluggish in a couple of years, not really going to be doing much that requires too much power on it (my desktop PC will take care of that), mostly browsing, word processing and light gaming. I will be getting a 27 inch cinema display to go with it so worried about the computer being able to run that display well. All things being equal i would rather get the air (top of the line 13 inch model) if it would get the job done for the next 3 years but if it won't i will get another 15inch MBP and deal with some back pain, maybe look into a better laptop bag for it or something. So i guess the question is the fully loaded 13 inch Air good enough for the next 3 years or should i look into a 15 inch MBP?
