TFA doesn't mention the size of their monitor, or the ratio of it, or the distance they typically sit from their monitor, or the horizontal placement (relative to their eyeballs), or the type of work they're doing.

I'd also expect a mention of the amount of curve they are upset about.

There's a few varieties, the 1500R and the 1800R were the most common two when I was shopping last year, in the AU domestic market. Those numbers refer to how the monitor might fit on an imagined circle's radius (measured in millimetres, naturally). So an 1800R is a gentler curve than a 1500R.

I find UW's beyond about 34" are mostly more comfortable in an 1800R for 'office work' activities (not including CAD, photo / image manipulation, etc) and gaming.

(I actually have a 43" flat, in 16:9, it sits about a metre from my eyeballs, and I usually aim for my eyes to be about 1/3 the way from the top of the screen. After several months with this, I now feel a gentle curve on this would be a bit more ergonomic.)
