So I am going to be going to college soon for a computer science major and I need some advice. I currently own a MacBook pro 13in from 2011. It's a good computer and I feel like it could handle coding and other things good enough. The problem is this thing is massive! I weigh 95 pounds ( I'm a girl, in case the computer science major through you off...) and have really scrawny arms so carrying the MBP around is a real pain. When I purchased it I didn't think the size would be that big of a deal. I thought 13in should be ultra portable but it really isn't with it's weight. I couldn't imagine carrying the MBP and books as well. So I am thinking about selling it, adding some money to it and going to a 11in or 13in MBA. My question is, for my uses which MBA would suit me best? Does it handle coding okay? The small screen isn't a big deal because I'm just going to hook it up to my bigger monitor at home. Does my current MBP handle programs better in anyway that would justify keeping it even with its size? Thanks!
