Hong Kong scientists have developed a robotic hand that allows people talking over the web to experience the sensation of touching each other — even feeling the strength of a handshake.

The cyber hand can grip and shake as well as make gestures and touch. The current model is expected to go on sale by Christmas for around $37 each.

I've got a beta version of this and I'm not convinced it's a good thing. For instance, I accidentally dialed the Vatican and now I can't find my underwear.
