Say* one is considering getting either the 11" 1.6GHz/4GB/128GB or the 13" 1.86GHz/4GB/128GB (or the Sandy Bridge equivalents whenever they come out).
They cost exactly the same, and the 13" has 24% more pixels, ~40% more battery life, a larger trackpad and function keys, and is ~10-20% faster (which is noticeable when the proc is the bottleneck; this number may change for the Sandy Bridge equivalents).
(And an SD card slot, and marginally better speakers, screen, hinge, and wrist-rest area.)
The only advantage of the 11" is being 9 ounces lighter**. This difference makes no significant difference at all when carrying it in a bag***, but only makes a (very small) difference while holding it or supporting it somewhere on the body.
I don't see any reason whatsoever for anyone to get the 11", at least over $1299.
(EDIT: Don't mean to be a jerk—I'm just interested in the reasons people have and in the debate)
* just for the sake of discussion; this generalizes to some extent to other configs
** and 0"x1"x1.4" smaller, and maybe some other not-really-significant details
*** Adam Engst recently shared the contents of his backpack. Say one's bag is half the weight. The difference in weight between the 11" and the 13" would be 6% of the bag
