So you’ve roughly doubled the number of parts, with risk of separating and losing them. It can be attached, but after locating and using an after-market device of unknown quality that requires initiative to set up. And then you have a power button in some weird place, not to mention now having to mind two power buttons. Some people will be confused when they turn on the monitor and nothing happens.

Anyone commenting on this forum is not going to mind looking after those parts and buying a mounting solution. Apple sells enough iMacs to show that most people have priorities and inclinations that differ from the people who comment on this forum.

You just explained it. Extra cables, potential mounting hardware… when disassembled is also more to pack up, move, and set back up.

You might not think it’s much harder, but it’s harder.
