Hey, I'm really torn between the two sizes, as they each have unique advantages over the other one. I think I definitely wanna keep the 10.5", for portabilities sake. But I'm thinking for example when I'm traveling, I would feel better with the 12.9" as a laptop replacement than just the small iPad for a period of two weeks or so. When at home and just freelancing around the local area, sitting in meetings to take some notes, the smaller one is actually nicer to carry along. I used to have the 12.9 for 1.5 years now and though I really have gotten used to the size, I definitely sometimes hesitated to bring it along, for the size alone!
