Oof! 16:10 display in a 13" chassis is tough to beat. Those extra vertical pixels make coding on it that much nicer. Way to go Dell! If only I could get 16:10 in a ThinkPad; I'm a sucker for their keyboards and trackpoint.
Honestly, it's way overdue. The widescreen style laptop has some uses ... but it really is a pain for so many things.
