I stopped using multiple monitors when I started using a keyboard-driven tiling window manager. At the time I had a 3-monitor setup in my office. I found that it was more efficient to switch applications by keyboard than to turn my head. I have used a single monitor ever since. At times I put 2 windows side-by-side, but mostly I display a single window at a time.
