Hi, I am thinking about buying a refurbished 13" rMBP 2.6GHz, dual core i5, 8gb ram, 516 flash storage. Can any one enlighten me on the difference between the Oct. 2013 and the July 2014 models beside the 2013 being $40 cheaper. Will one be more problematic than the other (flaking screen, faster FD)? I plan on using the lap top for web browsing/streaming, light photo editing, storage for music and movies. Basically this will be my main computer. I originally though about buying MB 12" but the 13" rMBP looks to be a better deal. I currently have a mid 2009 13"mbp. Any advice would be greatly appreciated.
