I've had my 13" MBAir 128GB about 16 months. No complaints at all, it's been a solid laptop. I'd like to pass it down to the girlfriend who is using a Sony Vaio and get a rMBPro... I don't much care about the storage because I store my data on my 2TB ATC, but the 15" retina would be a nice upgrade. I'd probably go with 256GB. Beyond that, is the performance upgrade worth it? Or should I wait? I mostly use it for personal web surfing and amateur photo/video editing... with occasional AutoCAD for work. Thoughts? Thanks!
