Bring the vertical resolution back! (1920*1200 not 1920*1080 ;-)
I find it strange that everything is going towards "wide" (and "glossy", but that's another issue).
I've seen a lot of seasoned laptop users complain about the decreasing vertical pixel count. And I totally agree: Most applications benefit from the added display lines. It might be that the display manufacturers just got it wrong - but I would suspect Dell to be a big enough player to have a say.
So please bring back the less-wide screen formats! :-)
