1 - I replaced 2x4k 27inch monitors, and so far so good, only annoyance is sometimes I want to share an entire screen as a reflex, I have to remember to have a more window focused workflow.
2 - The power brick is GIGANTIC, but it charges one of my laptops at 96w
3 - It is a bit blurry due to the antiglare coating. Might be annoying to some.
4 - The built-in USB hub is good enough for my Razer Kiyo Pro Ultra, and it gets switched to my active computer, unless I am using HDMI (no USB link available separately from the Thunderbolt or USB-C main ports)
In general, I wanted an Apple XDR display, but with multiple inputs. The results are not as good from an image point of view, but better from a productivity point of view.
