Better technology on its way?

Just wondering if anyone is aware of any new technology on the horizon that look promising in regards to hair removal. I recently came across this article on lasers and thought I would share it:

www.Nature.com

Maybe more precise laser technology like this could be used for hair removal and better permanent results could be achieved.

how about the new one that destroys hair by sound [dont know the name] seems a bit SUSPICIOUS to me, personally…

has anyone else heard of this too?
