This is technically a bit of a spoiler for the book, but a) a lot of them are not in the book, and b) the book comes out in half a year, and we’ll all forget by then!
Let’s start!
I use one of these for some hot keys for myself. Can’t beat a good arcade button. https://store.djtechtools.com/products/midi-fighter-spectra

That was actually the NeXT ADB keyboard, introduced IIRC about 1992. The original had a more conventional layout (https://en.wikipedia.org/wiki/NeXTcube).
The ADB keyboard certainly looked attractive, but for me at least the keys required far too much pressure to activate then had a very solid endpoint. The mouse similarly looked great but was an ergonomic disaster (presaging perhaps Apple’s later puck mouse). Together they gave me appalling RSI.

I typeset this book on the NeXT using FrameMaker and @tjt’s excellent equation editor, and Tailor to edit various PostScript images

Yes, I used that combination for perhaps a year.
Although a great innovation, the implementation of the Command Bar didn’t work well *for me*.
It was too narrow — my thumb joint used to regularly hit the *sharp* edge of the main body of the keyboard, and like the keys the actuation pressure was too great so the repetitive stress of having to press on it negated the value of using the thumb for the action. It also quickly became lopsided as I typically pressed on the right hand end.
