It was thus said that the Great Zane H. Healy once stated:
One of these days I'd like to find a really high quality USB
keyboard. While I do like keys tops that stay intact, I'm more
concerned with with the keyboard not twisting easily, and keys that
feel good when you push on them.
I got a keyboard/mouse PS/2 to USB connector, so I could use my PS/2
keyboard(s) on my Mac mini. Works like a charm.
