I will start college this fall and go for a CS degree. I have been waiting quite a while for the macbook refresh... and now it's finally here. I have a $2000 budget but would prefer not to spend it all. Below are the configurations I have built on the apple store. Macbook Air "13 256GB Flash 8GB RAM 1440 x 900 Resolution ~$1500 Air: lightweight, thin, higher resolution Macbook Pro "13 500GB HDD 256GB SSD (I would buy and install on my own) 8GB RAM(also buy and install myself) 1280 x 800 Resolution ~$1500 Pro: heavier than air and retina, thicker than air and retina, lowest resolution NOTE: The reason I waited for the refresh was because the Pro "13 has a 1280 x 800 resolution(low, low, low) Retina Pro "15 CRAZY RESOLUTION 256GB SSD 8GB RAM ~$2000 Retina: lighter than Pro but heavier than Air, about as thin as the Air, Flagship product, best resolution With the upgrades to the Pro and Air I can get similar specs as far as Storage and RAM go. So now the difference among the three computers is basically just the screen and structure(size and weight). Should I get the Retina Pro? Is the screen worth the $500 increase?
