I have two MacBook Pro's and I cannot decide which to put Parallels on for running Windows. I am taking some classes that require Visual Studio, Intel XDK, MS Visio. I also plan on taking more classes in IA. My older MBP is mid-2010 and the hard drive is about half full of 250gb and it has a cracked screen. My newer 2014 rMBP is brand new but it only has 128gb flash storage. I plan on keeping all of my iTunes stuff on the older one. Does anyone have any suggestions on what I should do?
