I tried multiple monitor setup for about 6 months and in the end I couldn't stand it. I used to put certain reference data on the second monitor - like a DB schema, or the layout of a particular communications flow etc...At first I liked it for that purpose. Then I started to get irritated at occasionally losing my cursor over the edge. Over time I also found myself glancing at it for no reason. Eventually I realized a paper print out of my schema or doc, sellotaped to the wall worked much better. I reverted to single. Much happier. As mentioned elsewhere a tiling window manager (I use i3) is the key to making this productive.
