Hi Guys, I am gonna start my Masters in mechanical engineering in this fall. Now I have an ageing 2011 MacBook Pro 13 inch ( with 8Gb ram ). Which I am gonna replace in the next two months. Before I had my mind set on a MacBook Pro 15inch with dGpu. But now I have another brainwave!! Why not get the base 13inch rMBP (Initially I decided on getting a Macbook but it won't be sufficient for my CAD/MATLAB/Simulink needs) plus an iMac 21inch with fusion drive + 16 gb ram and + GT 750M. Here I can store all my files and also use for gameplay whereas 13inch can be used for college purposes.
