I have been thinking about picking up a 2017 maxed out 13 inch. However the more I look at the 2017 15 inch it seems as if apple made that one ALOT more portable if this is the case I may just go with the 15 inch. Has anyone had experience with both of these? (the 2015 & 2017 15 inch) My needs would be met with the specced out 13 inch HOWEVER I do like the screen real estate and would go that route if the portability has improved drastically. (i own a 2015 15 ATM) thanks!
