But tbh it really depends on what you're gonna use it for.
If it's just for school and social media, maybe a Macbook Air will work for you.
If you're into photography/ video / graphic design / anything related to that, I'd recommend a Pro since they're better for that kind of stuff + the Retina display is just LIFE CHANGING.
I can't wait to get that! Since I do YouTube videos and photography
If you buy the non-retina macbook pro you can upgrade it later if you need (i upgraded the ram to 10GB recently myself it's very easy lmao) unlike the newer models (so keep in mind whatever specs your computer comes with like the RAM or storage capacity you're gonna be stuck with those if it is a Retina model).
Macbook - Retina Screen, under powered, light, small, good for traveling and light browser use, that's it.
Macbook Air - ****** screen, a little more powerful, but still light, and mainly for school and browsing.
Macbook Pro- 13" is pretty powerful, but if you need raw Power the 15" is best because quadcore, both have Retina Screens still pretty portable, the best bang for your buck
other thab that my Pro is wonderfully amazing <3
