Currently using the Dell 38" Ultrawide and very happy with it. The ability to select preset tiling arrangements is a plus for dedicated document real estate. Tiles can be customized as well. If you go that route, make sure you have the GPU to drive it. The other option I considered was the use of two 27" BenQ Designer series monitors, and with NX's docking options (to the other screen) this was really tempting. I sit ~33" from the monitor and so there's some scanning going on but I can't imagine it's any worse for me than sitting static for hours on end. Still on the fence as to which is the better option but I find it at least AS productive as dual monitors... and working with spreadsheets, databases, etc., is a plus to the widescreen, if you do a lot of that.
