Well, it's official. I'm like Goldilocks.
First, I tried the 13" porridge, but x800 resolution was too small.
Then, I tried the 17" porridge, which was nice and big, but too fucking big to us on a plane.
Then, I tried the 15" porridge, which was a nice compromise, but sadly, still too big to use on a plane if the guy in front of me decided to recline his seat.
So, after much ado (and a bunch of wasted money...) I picked up another 13" today. I wish it was a little better than 1280x800, but for $999 I couldn't pass it up. The form factor is definitely "just right" for the plane, it's easy to travel with, and it'll do netflix, movies, and a little WoW here and there with no problem, without being too hard on the purse strings.
Here's a shitty dark pic.
I wish I'd had the foresight to make images of each size so that I could just TM my apps onto it, and run SW Update, but hell, setting up a new machine is half the fun anyway.
A friend of mine just got the 13" MacBook Air.
Hot. Buttered. Sex.
