While it's not quite related to consoles, I've noticed that the non-GUI interface to a lot of operating systems often don't get a lot of love. Linux has had a fairly nice boot scroll, but I think part of that is because it's become an icon and as such is part of the public face of the OS; but on macOS for example it's an tiny awful experience because the text doesn't scale to 2x (you'd think Apple would be the first one to fix this…) and the output isn't well formatted at all–it's just the various subsystems spewing text as they start up. And a lot of modern systems use kind of old fonts that in many cases seemed to be picked as an afterthought…
