I know I said this on the Youtube comments, but it seems we have people enjoying a handbag fight on there at the moment, so I suspect comments may get lost.
For anyone interested in industrial design, the bloke who designed the Z88's mouldings has uploaded a load of his drawings and photos to Flickr.

This is what mine looks like (inside its vinyl dust cover). Yes, a rare colour Apple Z88 notebook!:
I was on work placement at Uni at the time, and we had just taken delivery of some Mac FX machines for CAD work. So I took the opportunity to borrow some stickers. You would not believe the number of people who Oooh'ed and Aaaar'ed over what looked like a super compact Apple portable computer.
At the same time, in another part of Cambridge, a company called Acorn were working on their Acorn RISC Machine, which nowadays really does power Apple portable computers!
On mine, there is no expansion connector in the side, but you can see where it should be in the moulding. I wonder what they had planned for that. Presumably floppy drives etc. The serial number on mine is 47,000 higher, so presumably a design revision happened somewhere along the line.
The "hard reset" switch is intended to protect the system when the memory modules are removed/inserted. Normally there would be a transparent plastic cover which flips down. Doing so would flip the switch and so power the system down (or at least put it in a sleep state) while the user was messing around.
