Funny that, as Cherry produced the switches for the IBM clicky keyboards (the product which was in fact produced by Lexmark)
They may well have done, but that didn't stop them cornering the cheap end of the market as well. When IBM XT and ATs were being made, the so-called IBM-'clones' often came with a Cherry keyboard. It's too many years ago to remember for certain, but like I said I recall they were c*ap - little feedback, vague, soft-click, that sort of thing. People at work were walking off with the genuine IBM boards for use at home - so much so there was a critical shortage at one point and they secured them to the base unit making them more difficult to nick
