The Virtues of a Second Screen

Perhaps I'm doing it wrong?
I have never felt a big benefit from multiple monitors, or even especially big monitors. 95% of the time I'm working with text, and I can only comprehend one window of text at a time. As long as I can flit around between multiple buffers, tabs, or desktops without my hands leaving the keyboard I'm fine.
Most of the time I'm in "Development" and the left monitor is a fullscreen terminal with documentation/revision control/program output and the right is fullscreen gvim.
Nothing is more important to me than resolution though. I can't deal with anything less than 1600x1200 and almost always run 1920x1200 on everything (including laptop).
