My computer keyboard history, for keyboards that I liked or loved¹:
[many] → NCD Unix keyboard (relatively unobtanium even at the time) → [assortment] → BTC-5100C compact keyboard (PS/2 only, PS/2 is dead now) → Matias Mini Quiet Pro (fine but keys eventually kept sticking) → WASD Code 87 with Cherry MX Blues (out of production, keycaps wearing).
Yes I have used an IBM Model M. It's a perfectly okay keyboard.
¹ I've used a lot of keyboards over the years; only some of them stick in my mind.
