Now this is a fantastic idea: PFU offer a variant of their Happy hacking keyboard that has blank key tops! The Happy hacking keyboard Professional is only for the elite few who never have to look at keys.

Nevertheless, I'm not going to use it. I've been a great fan of the Kinesis Classic for some years now, using the Dvorak layout (also see here), of course. Similar to the HHKB Professional, nobody wants to borrow it very often :-)

I wonder what makes other people type fastest?
