I currently have a 13" MacBook Air and want to upgrade to the new 2016 MacBook Pro. I can't decide if I want the 13" or 15" model. I am a web developer and also do some app development in Xcode. The price difference isn't a concern but the size and weight of the 15" model is. I could really use a higher resolution screen and the extra power of the CPU and graphics in the 15" model. Has anyone made the upgrade to a 15" MacBook Pro from a MacBook Air? If so are you glad you did or is the extra size and weight noticeable? I primarily do my work at a desk, on the couch, and in bed. I don't take the laptop with me to meetings.
