Hello, I'm currently writing this from a 2009 13" MBP 2.53 Ghz 4GB RAM. It's been three years, and I want to upgrade my computer. It's not simply that this computer is "getting old." It's been running pretty slow recently, especially ever since I've started to try Virtualbox. I'm one for performance, and the performance that I've been getting out of this computer doesn't feel acceptable. I was considering waiting out until Haswell next year, but with Intel basically releasing a new chip every year at this point, I figure now is as good a time to upgrade as any (not to mention that I probably need to). I'm a computer science major in college. Several times I've been told not to buy the MBA because of the ULV processor. This is a big issue, as I have been looking into a Quad-Core i7 processor, especially considering the possibility that I may want multiple VMs running in the near future. The lack of a discrete graphics card and decent VRAM is something that I could also see contributing to poor performance, especially on both emulated OSs as emulated mobile devices. Add in taxing processes on Terminal, and I'm definitely not a computer user that you'd consider lightweight (even though I don't do any video/photo editing). I may game once in a while, but that would be the rare game (although some of those games would also be done in a VM). Even though I've mentioned that the MBA does not fit many of the things I've thought I've needed (and am still not sure on), it cheaply gives me three things that I do want - IvyBridge, SSD, and a minimum 8GB of RAM. For this reason I originally considered the new RMBP. Now, the RMBP is quite the investment, and one that probably wouldn't be upgraded for a while (which I'm not too fond of). I'd probably be paying $2,180 for the base model +16GB RAM (after student discount) (about $940 more than the RMBP I would be facing it against). So, allow me to get straight to the point: Will the 2012 13" MBA @ 1.8 GHz i5 8 GB RAM/$1240 fit my needs? Or do I need to look to a higher model to get the computing power that I desire? Right now I feel that the RMBP is my only recourse, but please sure your experiences of multiple VMs/games - I'd be happy to spend less money (and upgrade sooner in the future). Thanks.
