Heh OK... um. I think. Now I'M confused.
Fwiw (if we're misunderstanding each other)... having 1920x1200 on a 15" laptop right now is utterly ridiculous and silly. Without a RI GUI there's not much point unless you have a masochistic enjoyment of eye strain.
Windows sort of deals with it by increasing font sizes and whatnot but its a pretty piss-poor attempt at RI (omg lets increase all the web graphics by 125% that looks great!!! Not. Stupid MS)
