The all in one computer is not new. For example:

Atari ST/STE/Falcon, Commodore Amiga 500/1000, and Sinclair QL were all-in-the-keyboard designs (disk drives and all).

The design had one major flaw, which was fixable, but fairly costly in manufacture. Anything socketed like a chip or cable would eventually come loose due to heavy vibration by the typer. To this day, I fondly remember Atari’s recommended fix for the Atari 1040ST’s that would come back to stores for repair (I worked at Federated Group back then, an Atari owned electronics store). They told you to (out of site of the customer) firmly grab both sides of the computer, using both arms for leverage, and firmly twist the entire structure of the computer a few times. This “trick” effectively re-seated the chips that worked themselves loose! The customer was happy (as you kept it a few hours to show “work”) as you charged nothing for it and it was prompt service.

The permanent fix was to install retention braces for all of the chips and use locking cable connectors at the time of manufacture, and to make sure the soldering of everything was top notch.
