Despite all the people talking about curved not causing distortion, it definitely does: if you are anywhere other than perfectly at vertical eye level with the line that you're looking at. My excel spreadsheet grid lines look curved if I'm standing above my monitor or below, even slightly. What's more, for the first 2 months, I kept trying to turn and adjust my monitor because I thought it was misaligned and not perpendicular to my view. So many times I reached for the edge to twist it before realizing, oh yeah, it's curved.
I'd buy it again if it were a free option. But not for a +$220 premium.
