I currently have a late 2013 13" rMBP 8GB/256GB. Bought on July 31, 2014. I mainly just use it at home, sometimes take it to work, but it mostly stays on the couch with me. Not sure why, but I recently got the itch to get an 13" Air. IF I was to switch, what would be most comparable? Should I get the i5 or i7? Stick with 8GB, or would 4GB be ok? The main use is web browsing, watching videos, etc. I use iTunes and iPhoto, but don't do any serious editing, etc. I also use it to remote in to my work machine.
