Does anyone have experience running software like Matlab and Mathematica in OS X and can comment on the performance? I am beginning a graduate program in aerospace engineering and am in the market for a new laptop, since almost all the work I'll be doing will be off campus. I'm a longtime macbook pro user (currently have a ~2010 13" C2D) and am seriously considering the new high end 15" rMBP. My one reservation is that I will get better performance out of both of those programs from a native Windows machine. I've seen reports of them running noticeably faster in VMware/Parallels, which seems very counter-intuitive. My other options are the new Dell M3800 or the older Asus UX51VZ. Loyalty aside, I just want a machine that will comfortably see me through the next three years. I doubt I'll have to do any solid works/AutoCAD, but it's not unreasonable that I'll run into some other software that forces me into Windows. If I can make the MBP work, that's my first choice, but I'm not getting rid of my 13" MBP just yet, so I still have OS X for leisure use. Thanks for the help!
