So, I'm a web developer and do a lot of coding, I currently have a dual-monitor setup with a 2011 Mac mini and I have to say: it's lovely and runs loads of apps at once - no problems what so ever. However, I'm starting work for more and more clients at their various offices every week and need something portable. Hence, MBA. But, my biggest question is this, does anyone else feel that the 11"/13" display is cramped? Currently, my 17" display at home is 1280x1024 giving me loads of height to view code, while my 1600x900 main monitor shows the website. But, if I were to move to a Macbook Air, after a whole day on such a tiny screen, with/without an external screen, will the small screen size get to me? I have thought about purchasing one and if I don't like it then returning it within the 2 weeks. I've also thought about the 15" rMBP. Any thoughts? What have you guys experienced? Much appreciated.
