Hey guys, first thread I've made on here so go easy. Basically I've been told I could have a MBA for university (september 2012) which I would be buying around January 2012. I'm hopefully going to be an engineering student and dont want to waste my money getting a 13" MBA due to the fact that I have an ultra portable iPad, iPhone 4S and then a desktop 21.5" iMac for the more heavy work. If I were studying anything other then a science that involves design work, I would have thought I could get away with my iPad but engineering will require a lot of word processing and some light design work. I'm happy enough getting the 13" MBA but I just don't want it to make either my iPad seem a waste of time, or my iMac result in becoming a media hub and nothing else. I am tempted by a 15" MBP but I like the idea of the weight and ssd the mba will have. What do you reckon? Thanks Also, when is the MBA refresh usually out of interest?
