I would rather have one huge screen then multiple small ones. I work my apps full screen and it is very easy in Windows using a Microsoft optical to just press the scroller down and jump between apps. The only time I liked multiple monitors was when I was using Photoshop on a 68K mac when the pallete is on one monitor and your work is on the other. I also use dual monitors for video editing.

Currently I kind of like the 19" LCD I have, it is only 1280x1024 but I like the text size compared to my old Sony 19" CRT that did 1600x1200. Widescreens just don't do it for me for a PC monitor.
