been trying to read & learn la ot here, I keep seeing "future-proof."in some threads as well as "haswell processor" , VM's and "bootcamp". obviously I have little to no idea what all of this means, trying to keep a purchase as secret to my son http://forums.macrumors.com/showthread.php?t=1686924 at the same time , pretty wary of buying something that is not upgradable or getting stuck with the wrong mac. use (that I know off ) Adobe full suite X-code Blender 3-D Maya settled on 2 macs. 1.) Refurbished 15.4-inch MacBook Pro 2.4GHz Quad-core Intel i7 with Retina Display Originally released February 2013 15.4-inch (diagonal) Retina display; 2880-by-1800 resolution at 220 pixels per inch 8GB of 1600MHz DDR3L SDRAM 256GB Flash Storage 720p FaceTime HD Camera NVIDIA GeForce GT 650M with 1GB of GDDR5 memory $1659 or so 2.) 13" MBP (non-retina) 2.9GHz Dual-core Intel Core i7, Turbo Boost up to 3.6GHz 8GB 1600MHz DDR3 SDRAM — 2x4GB 128GB Solid State Drive $1400 or so. ***** #1 seems like the better choice, drawbacks are only 8 GBS, can't upgrade at all, pros are Quad core AND 1 GB video card. #2 is a dual core, but it IS up-gradable up to 32 GB (if they ever release that, I heard I can get 16 GBs mem for it) seems SOME of the threads who talk about "future proof" mention 16 GBs on all of them, , should I be worried at all? or just spring for #1? EDIT, THANKS for the help AND the patience.
