I love having a dual-screen setup at the office, but at home I didn't like it much. Part of it is the layout -- most of the stuff at home only uses the one screen (e.g. playing a game) at which point the screen positioning becomes an issue. Either you always have to look sideways since your primary screen is centered in front of you, or your secondary screen is too much off to the side to be really useful when you do need it.
