Thats what I thought too until when use 13inch then horny want a 15inch..

But nowdays Apple spec-ed up the 15inch .. so exp... :/ I just want a larger screen to use.
Too bad Apple dont have 32inch .. only 27inch in my budget range.. Thunderbolt display... so sexy .. full alu back..
I already feel my personal 15inch so heavy .. but back then its better than 15inch from previous generation.

I'm still using the first retina mbp from 2012.

But for home now I want a 27inch..
