So I am wondering whether I should invest in a curved screen
I would think the answer to that, depends on how you use your screen. Personally, I wouldn't swap my two screens for a singular one (curved or otherwise) because I would lose some of the functionality (the ability to have one screen in full screen with either a game, video or some other media medium and the other in tabs or small windows). I'm not sure that would work well with one singular screen (games would try to take up the entire screen of a wide monitor). I would probably have to change settings in the game(s) to stop it doing that, but it's just one more hassle when I want to exist in a world of as few mouse clicks as possible.
At the moment, I have my two screens set up in a wide 'V' with my eyes naturally pointing at the middle bezels. I'm sat in a swivel chair, so it doesn't take much for me to change angle sightly to meet each screen head on. As for typing straight on to the screen, I just move the keyboard slightly.
I thought at first, the bezel in the middle would annoy me (back in the day), but I grew up with CRT's being my multi monitor setup, and the race tracks that used to surround them, so I have grown used to having the equivalent of an RSG in front of my eyes. Now, bezels are really thin and if you angle (position) one screen slightly behind the other, you in effect only have the one bezel. I may have a curved screen in the future as my main and keep one of my existing flat screens as the second, but in all honesty, I haven't seen much need in swapping to a curved screen. In fact, I'm still a little dubious about curved screens being anything more than a marketing gimmick.
