Hey guys! So I currently have a 2013 13" Air with 8GB Ram and 256GB SSD and it's still getting all my needs done like a champ. I have been thinking about possibly upgrading to a pro for the better screen resolution, and I was thinking about getting maybe a 2015 pro? I've tried the new keyboard on the new macbooks and I really do not like them and as someone who uses their SD and USB slots daily I'm thinking about going for the 2015, additional plus that it also still has the magsafe. Now Somethings that I'm worried about.... Because it is older tech, should I look for a spec bumped version to future-proof it better? How's the battery life? I figured with a better screen, it would drain more and I do love my air's battery life. Finally is it worth it in the long run? Or should I just sick it out with my air?
