I remember reading about Steve Roberts building chording keyboards into his "handlebars" on his Winnebiko years ago. Since he had well more than 2^5 bits using both hands[1], he was able to assign macros that helped significantly with his effective typing speed. Englebart says that his layout is not intended for speed typing, with the typical trained typer being able to type 30-50wpm. He observed that typing speed on conventional keyboards does not have a strong correlation with typing speed on his chording layout. Sight-reading piano players have a bit of an advantage here, of course. I've always wanted one of the Twiddlers, and am kind of excited they're back on the market, but I'd vastly prefer a wireless version. I've also been looking forward to the release of the FrogPad. It would be nice to have a better-than-touchscreen keyboard for emails on the iPad or iPhone. [1] I can't remember the exact layout now. If it used all ten fingers, or if it had multiple positions for, say, thumbs, à la the BAT keyboard, it's gone from my memory. Regardless, it used both hands.
