It also ties you to a desk. If you're working in one location, a desktop PC would be more cost-effective and more performant. If you need mobility between desks, a small form factor PC would be easier to carry. And if you are an employer and expect employees to work from home on this keyboard, you need to buy monitors for their homes.
The first thing I thought of when I saw this was using a phone as the display. Not as good as an actual monitor, but a far more interesting setup than what you're imagining.

But ugly and taking up space, which is why the iMac exists and has been pretty successful for decades at this point.

Maybe, but performant AR glasses are changing that equation. The cyberdeck, as an ideal, still exists for a reason.

Do you? Is that law where you live? Because it's definitely not here in UK. I'd rather work on my trusty 4k than some shitty cheapo Dell only provided to tick a box.
