I have a 2011 MBA, fully upgraded. Works great. But recently, I started recording screencasts. Fan goes crazy, things slow down. I want to upgrade. I was thinking of getting the 2013 MBA, fully upgraded. Will this be enough for my needs? I'd rather have an air than a pro, I love how portable and fast it is. I'd be recording screencasts with Screenflow, and editing them. Or making screen recordings with Quicktime. I'd like my machine not to be super taxed while doing that.
