My current setup is 21.5 inch iMac @ 1920x1080 & 22 inches Dell, vertically @ 1050x1680. I prefer 2 screens instead of 1 big screen. The reason is simple enough: I would like to watch movie and monitoring another stuff at the same time (quick glance for every 3-5 minutes or so). Having 1 screen would force me to either not go fullscreen (quite hard to enjoy the movie) or switch context all the time. Also multiple screens give you this sense of "border" where you can feel natural to snap them to the edges.
