I am thinking of selling my early 2013 base model 15" MBPr and getting the 13" 8gb 512gb or. My wife has a Early 2013 13" Base so have compared size and would like the 13" plus i need more storage. Will i notice much difference good or bad between the 2? I don't game or do too much heavy stuff. Mainly photos and video in iPhoto/imovie.
