The question is how much OLED and 240Hz is worth to you. I am satisfied with the monitor, but the price is not to be scoffed at and should perhaps be interpreted as an indication that it is still "early"...
Note OLED: WOLED is used, which leads to somewhat unsightly text display. This is not a problem in games, but if you also want to work on the monitor, it is a negative point. Even though the effect doesn't bother me personally, it is clearly visible.
Note 240Hz: I think the high refresh rate is worth it if you a) play games that have a high FPS limit or no FPS limit at all, b) actually notice the effect, and c) have the necessary power to achieve the necessary FPS numbers (e.g. over 100) in games. I think a) and c) are certainly fulfilled here, and I assume b). But with b) comes point d): having the necessary small change to be able to finance high system performance in the future, because after a certain time with a 240Hz experience there will be little willingness to step back to 60Hz.

Hello, I bought the AQDM at the beginning of July.
It is a good monitor, which also scored well in Hardware Unboxed.
The colours are what I expect from an OLED. I'm not sure, because I haven't had any long-term experience with it yet, how it behaves with the burn-in.
So far I haven't noticed any burn-in with the taskbar and screen saver hidden.
