I've held out for a long time waiting for updates from Apple and for my use I'm going to continue to wait. However, I'm buying for a student who must have a laptop computer by September. I'm not buying used so I'm thinking the best value is the base 13 inch rMBP. The 13 inch Air's aren't that much cheaper but their specs are significantly worse than the Pros. Given that I can't wait for Skylake, at this point what are your opinions on my best Apple options?
