I have a 2011 MacBook Pro 15". It has two hard drives in it including a SATA III SSD, and 16G RAM. It's still running strong. I can't imagine why Apple has not been able to improve on the computer's specifications for serious professional engineer use in five years. The CPU increase and GPU increase is unimpressive. (Why no quad core in 13"?) Retina is fantastic, but not a substitute for proper amounts of memory. The only major improvement is the awesome bandwidth of the 1T SSD in the new models. I use the F-keys extensively in my workflow. I could barely even reliably hit the ESC key at the Apple Store when testing vi. The keyboard was also atrocious, but I would probably adjust if it had F-keys. The bottom line is this is just not a useful laptop for me. Super sad, cause I would have liked a top-of-the-line computer. I am going to get an Alienware 13R3 or Razer Blade instead. Sorry, Apple, you've taken too long to put out a reasonable professional laptop.
