I don't think I'll make the switch back anytime soon, because having a single monitor instead of two has been such a more comfortable way to work. Admittedly, the design of the UltraSharp 40 has a lot to do with why it's such a great replacement for a dual-monitor setup. It's over 3 feet wide, for starters, with a nice 2500R curve that makes the far corners of this broad display feel a little closer and easier to see. It replicates the feeling of being flanked by two displays without having any open air in the middle, so you don't have to look at your office wallpaper unless you want to.
