But the XT layout... ugh.
Back when they first came out (actually it was the original PC, not even an XT), I fell in love with the keyboard and it didn't even bother me much about the layout. The feel of the keys when typing was simply the best I'd experienced in the computer world, and the closest experience to typing on a Selectric.
When the AT keyboard came out, I switched and it took a bit of getting used to, but after that I wouldn't really want to go back to an XT. I think though that my biggest complaint with the XT layout was the Printscreen key's location. I recall I frequently accidentally pressed it when aiming for the Enter or Right Shift, sometimes sending my computer off into Never Never Land for several seconds while it tried to print the screen to a non-existent printer. Of course I was using PC-DOS, and the cursor would do a left/right, up/down scan of the screen as it attempted to print each character on the screen. As you say though, not a big deal these days as it could easily be remapped elsewhere, and that key be made to be a dead key. Better yet if a longer shift key could be swapped in to cover both the present Right Shift and Printscreen keys. Likewise a longer shift key on the left would be good, but then where to put the Backslash? I use the Backslash all the time so wouldn't want it out of reach where I had to move my hand off the home row position.
One of these days I'll have to look inside the XT keyboard and see how difficult it would be to make a new controller for it so it could be used with modern computers.
