The 3270 had the finest, strongest, most industrial strength keyboard in the known universe.
When I was at RPI, we were still in the mainframe universe and there were real, gen-u-wine IBM 3277 terminals and cheap Courier knockoffs around campus. Now I learned to type on a manual typewriter, and I have large hands. If I was using a Courier, I would regularly attract people who came by wondering what the hell all the noise was and/or whether I was beating on the terminal with a hammer. The IBM keyboards, though, were solid. I've always said that I want to have a couple of them nearby when the vandals storm the computer room. You could drive away the invaders and go right back to coding.
