HP has been too much all over the map with their prognostications. I think they're mostly trying to hang on to their jobs. As fantastic as the technology sounds, I think it probably has a long ways to go in the lab-fabs before it makes it to production -- if that ever even happens. Just the other day Samsung said it would cost $10B to build a fab that can produce memristor memory. I can't find that link anymore, but it sure sounds like there's a lot that's not being said.
