Hi everyone, First post here. I'm going back to school this August and need a new computer. It will mostly be used for typical school stuff, web browsing, music recording and casual gaming. Here's my dilemma. Originally I was going to go for the refurb rMBP for $1600, 2.3 ghz quad core i7 with the geforce 650m. Seemed like a good deal. However, I'm wondering if perhaps a 2013 air would be better for me. With upgraded 8 gb of ram and the education pricing it comes to about $1340. The mobility and battery life are really starting to grow on me and I'm still slightly hesitant about buying a model that's already a year old in the pro. What do you all think would be a better investment for the next four years? Edit: I'll be starting school in the beginning of August so waiting for a mbp update probably isn't realistic.
