Thought I'd get some info from those who've been around Macs longer than me... I'm comparing a late 2011 15" MPB with the 2012 version. I can get the 2011 with the i7 2.5 and high resolution anti glare screen for around $1400 from Microcenter. I'd upgrade the RAM as soon as possible and consider a SSD later. My main concern is the difference in speed and longevity between the 2011 and the 2012 (for comparison, I'm looking at the 2.6 i7). I'm a 'typical' user...productivity, photo editing, general home use, etc. Any thoughts?
