Well, I'm not thrilled about 768p but it's on a fairly small display, so not really much lower PPI than a 17.3" 1080p. Besides, resolution is not the only measure of a monitor's quality. If it was, there'd be no reason to ever test them. Similarly, two evenly spec'd 13" devices are not guaranteed to be the same quality, thickness, etc. Maybe this thing is really thin and premium built. Not that I'd ever buy one, but it looks nice from the pics.
Anyway, it's still at least $100 too high.
