I have a curved ultra-wide monitor, and I like the curvature
As a matter of personal interest what do you do on the monitor? I used one briefly and found it was horrible when doing anything like drawing, graphic design, photo editing, etc. It seemed to mess with the perspective.
Coding mostly, editor/IDE in the middle, debug output/IDE errors window on the right, browser window with docs on the left. With my laptop display open and used for email/Hipchat. I try to keep functions relatively short so they almost always fit within the vertical space of the monitor.
