For anyone that did this... bought the 13" this year and moved to 15"... did you notice the larger footprint enough that it bothered you? I travel all the time, but I am in FC 99% of the time, so plenty of space, and I'm really interested in the larger screen, but don't want the laptop to feel huge.
The better battery life will be a plus too, of course, but the main driver for the switch would be the screen.
