Wow, you indicate that EVERYONE prefers curved after using them, but I'm not sure how you were able to talk to EVERYONE?! Then, you also claim other people are ignorant.So far everyone (and I mean everyone) that has used 30" curved screen eventually admitted that curved is necessary on such a large screen. Why? Because you don't want such a variance of distance from your eyes from the center of the screen to the side of the screen. It is just not comfortable to work on large flatscreen panels on the edges. Another reason is that you normally only one person working on the PC, while this is not always true for Curved TVs I am sure that curved monitors will break through the ignorance barrier.Waiting for "curved" to die out like "3D." More on this FreeSync and G-Sync tech!
You're right about the comfort of having the outside edges of the screen the same distance from you eyes. However, the content that you are viewing now has the incorrect perspective. If you stand closely to a curved window, you will see more of the outside world than a flat window. Because the curve allows the perspective to see more from the sides, not just what's directly in front of you.
If you look at a curved monitor from a close distance, but it is displaying a perspective of what's directly in front of you, this is incorrect geometry! At a close distance you *should* be able to see more from the sides from a curved display, not just what is straight in front of you. If what is straight in front of you is curved around you by the screen, you gain an incorrect perspective. The curved screen may be more comfortable, but the content is incorrect for that perspective.
Imagine watching a televised tennis match from rear court perspective sitting close to a curved TV as you would a computer monitor. The tennis net and back court lines shouldn't curve around you, it should be dead straight. If the content has been filmed special for a curved display (through some sort of calibrated lens), the tennis net would be appear perfectly straight on the curved display, and you would gain peripheral vision perspective from the sides, such as the stadium crowd.
If the content was filmed traditionally flat, and you watch it on a curved screen, the net will be incorrectly curved around your perspective. This is wrong!
All games and movies are made for a flat screen. Until they start making content for curved displays, the perspective will be incorrect. They will never be able to make content for curved displays with accurate perspective without the knowledge of the exact screen size, and distance the viewer is sitting.
Numerous videophiles have been debating the problem with perspective and curved displays. It's a common topic on AVSforums. If you are unaware of this issue, it is you who has to break through the ignorance barrier.
Great lengths are taken from flight simulator fanatics to make sure that every display in their simulator displays the correct perspective. If you have 3 screens in front of you and you turn the two outside screens on an angle, the simulator software needs to know that exact angle in order to display the correct perspective. If you're just watching flat content with the two outside monitors angled towards you, you are viewing the wrong perspective! The same problem exists on curved displays.
As such, curved displays are gimmicks until the problem of geometry and perspective are solved.
