One thing regarding resolution/screen size: I think as of now, the Rentina MBPs are the only systems (besides mobile) that handle high PPI screens properly. Whenever you have small screen and high resolution paired together, on most desktops/laptops, you get incredibly tiny everything -- and suddenly you have to strain your eyes a lot to see things (which is something I'd rather not do). Density independence[1] for desktop OSes is a serious yet-unresolved issue, and without it I don't see ultra-high PPI desktops/laptops becoming common. I personally prefer lower PPIs (on desktops) than most people. The 13-inch MBA's ~127 PPI is almost pushing it, for me. On the other hand, I love high PPI screens on mobile, as the text looks much sharper and crisper.
