> if we're doing "the image generators don't get details right", it would seem to be there a lot simpler examples than OPs

There are different sorts of details though, and the distinctions are both useful and interesting to understanding the state of the art. If "man drinking coke" produces someone with 6 fingers holding a glass of water that's completely different from producing someone with 5 fingers holding a can of pepsi.

Notice that none of the images in your example got the function key placement correct. Clearly the model knows what a relatively modern keyboard is, and it even has some concept of a vaguely retro looking mechanical keyboard. However indeed I'm inclined to agree with OP that it has approximately zero idea what an "IBM model F" keyboard is. I'm not sure that's a failure of the model though - as you point out, it's an ancient and fairly obscure product.
