Oh, I misunderstood. When you said screen only, I was thinking an all-in-one, but sounds like you were meaning something more like a tablet.

You can get a mini computer and mount it to the VESA mounting point on the rear of a compatible monitor. Not quite screen only, but pretty close and has roughly the same footprint aside from a little extra cabling.

It’s a letter called a thorn. Its from old English, and was used for the ‘th’ sound. Its been largely removed from the languages that used to use it. I dunno why they have decided to try to bring it back, but that’s what the letter is.
