I for one like dual monitors. I use one for useless email, and IM. The other for real work(in between all hands meetings).

I wind up using dual monitors for cross referencing applications, where one screen has a drawing in AutoCad, and another screen for modeling hydraulics (a calculation app) and a pdf of a pump curve. Quad screens I have used for control of process units (chemical plant).
