Yes, they're alive and well.  The Twiddler (gotta love the name) is probably
the best known, as they've been written up a few times as the keyboard of
for the people at MIT developing wearable computing gear.  See
for more info.  Other one-handed chording keyboards
available include CyKey from Bellaire Electronics (,
MonoManus from ElmEntry Enterprises ( and the
Bat Personal Keyboard (  Prices for these are typically
in the $150 - $200 U.S. range.

With practice, people using one handed chording keyboards can usually get
typing speeds approaching 60 wpm, which is about the low-end of professional
touch-typing speeds on QWERTY boards.
