I really think that it depends upon the manufacturer of the display, and your experience with screens.
I love my 17 WSXGA+ screen, I can have two browser windows open and see pretty much everything in both of them without having to left or right scroll.
On the other hand the rest of my family is used to your regular "square" screens, as they put it. I guess theyre used to not seeing the desktop too much or they like the dedicated window to what ever they are running at the moment. Multi task!!!
