I was originally thinking of an IBM RT3200 keyboard, which I bought in 2005 or so, and which has a PS/2 interface.

The modern incarnation, which I'm using now is the Lenovo KU-1255, which I have grown to prefer, because I prefer the low-travel, laptop-like keys. Some people call them "chiclet", but I never used the original "chiclet" keyboard, so I can't say.

Anyway, the link you want is...

The other thing about the ThinkPad-inspired keyboards is that the mouse button arrangement reminds me of the "Leap" keys on the Canon Cat, and every so often I wonder what it would be like to use them in that fashion.

These are the only two that I know of. The first is the Tex Yoda, and the second a Lenovo product.
