Three Happy Hacking Keyboards
This means I have two Professional 2 with no keytops, one white and one black. The white keyboard will be used on my new workstation and the black will probably travel with my laptop.
Topre switches FTW!
I also have one of the original HHKB, as you can see on the photo above. The original has an equally great Sun Type 3-like layout but it's otherwise an ordinary, but good, rubber dome keyboard.
You might also be interested in a description of my own keyboard layout which also serves as instructions on how to remap your keyboard using the XKB extension without touching system files.
