Smallest good DV video camera?

I’ve got a Sony PC-9 (I believe that’s the one) DV video camera. Works fine, we video a lot and make DVDs and all is well. But even though it was the smallest DV cam I could find back in its day, it is still a bit bulky to carry around in a pocket and thus there are times that I wish that I had it with me that I don’t.

What’s the smallest good DV video camera out there today? Is there anything the size of, say, my wife’s Pentax Optio S digital still camera (fits in an Altoid can?)
