As cynical as I am when it comes to Commodore we are talking about the company that opted to use a nonstandard 3.5 mounting mechanism inside the A500 case and went about designing, producing and assembling its own eject tab for the floppy drive even though a standard 3.5" mount and face plate would have worked wonderfully well with the case.

The way I look at it, any cost cutting design decisions made by Commodore were most likely coincidental.

It's the same eject button as is in a normal faceplate equipped thick Chinon drive. So no, they didn't design all that much themselves, at least initially. :-) The A500 drive just has a notch in the cover and is missing the face plate.

Is it just me, or does this sound like it was sampled for the music in Arabian Nights? (1h29m16s)

Interesting. Not sampled, but surely sounds similar!
To be fair, it could be a coincidence. Use of standard 80s/90s synths plus a middle eastern-sounding scale will get you there.

Maybe they seen it as a means of quick temporary connection of peripherals and not intended for long term connections to the machine.
My suspicion would be so that sidecar add-ons using it wouldn't have a huge (and flimsy) pcmcia interface poking out the side - rather a lower profile interface, but I may be completely off the mark =)

It only takes a minute to reach the conclusion that sidecar devices are kept installed with the connector tucked away safely inside the computer while normal cards will always be at risk since they protrude from the computer when installed.

Here's another one, as I'm sat here writing adfs to disk for my A500.

Why do some floppies make a strange knocking or like shaking noise while spinning. I'm not talking about the noise of the heads moving between tracks but it's like a constant noise under that. Always makes me think the disk is going to fail.

Dirt or fungus inside the plastic case between the magnetic disc and the felt coating. It will eventually damage the disc. If it's fungus, it will also damage the drive.

Yes, a periodic knocking sound happens when something is stuck to the rotating disc so that every time it passes the head, you hear a knock. A constant whine means that it is just generally dirty.

I don't think it was all that nonstandard. The IBM PS/2 was around that time and it had a similar floppy setup where the faceplate was part of the case and not the drive. A couple of the old Compaq deskpro's copied that same idea as well. So while it wasn't an official standard across manufacturers it was common practice.

IIRC the crApple's were the same as well.

While many Apple machines did indeed integrate the faceplate into the casing, they also had non-standard drives - they had variable rotation speed depending on the track being read for the old Mac formats, and they had an electromechanical eject system, meaning dragging a floppy's icon onto the trashcan would physically eject the floppy, just like a CD would.
