Ok finally I've decided to get the 15' (instead of 13') this weekend on the Florida tax break. Currently I have a 13' Early 2011 with SSD and 16GB for web dev, photoshop and iMovie tasks, I'm wondering if I can get by with the 15' 8GB/SSD Late 2013 from the refurb store for $1500 or I'll need the $1999 for the extra 16GB to match my previous 2011 memory. I think the higher end model for $2500 is too expensive and with dedicated graphics is out of the question as I do not game on PC and the extra video card will not do any good to me for web dev. I'll love to same money but I do not want to go down in performance if 8GBn the 15' will not be enough as I was using 16GB on the early 2011. Any input will be appreciated.
