I object to this labelling: the term “all-in-one PC” has always been used to mean a computer integrated into a screen, to which you must add a keyboard and mouse (or more likely it will be bundled with a low-quality keyboard and mouse). But this is a computer integrated into a (good) keyboard, to which you must add a screen and mouse—and screens are more expensive than keyboards. Even a basic not-too-horrible screen will cost another $80, and the sort of screen you might like to pair with such a keyboard might be double that.
