I've been using 27" monitors for years now. I find that I put my work in the middle and use the periphery as window storage for ancillary context windows. (Like tailing server logs and performance tickers that I peek at from time to time while developing.) I also use a different virtual desktop for each set of tasks. (email/hn, development, research, …) I do add a second monitor when debugging full screen applications, but find I don't use it otherwise. An important variable here: My eyes have reached an age where they are no longer variable focus devices. My computer glasses are set to a fixed distance, so the center of the screen is in focus, but by the time I pivot over to the edge of my monitor, the focus is not sharp anymore.
