I've found vertical-oriented monitors to be just 'blah' for what I do (Windows/C# development.) Many of the Windows IDEs out there seem to realize that monitors are wider than they are tall, so various tool panels in the tool are on the right and left of the editor. Between the space used up for line numbers, breakpoints, resharper annotations, and other trim on the left, plus the solution explorer (file tree) on the right, there's only about enough room for 100-120 character lines in the editor. My IDEs are about the only thing that I run full-screen. The other monitors have multiple windows open, sometimes docked split left-right and sometimes slightly overlapping. Windows makes this easier with left-right auto dock, where it doesn't have up-down docking.
