DVD Killer?

I just read about this in the latest Wired Magazine -- NTT's Info-MICA cards -- thin film holographic memory cards, the size of postage stamps and carrying 1GB of storage to start off with. (NTT is working on higher capacity cards -- hoping to hit 10GB.) The cards are made of plastic, and therefore recyclable -- unlike other thin films that contain metal. They're small. They're cheap. They consume low energy to access, as there's nothing to spin. They can be easily mass produced. And will probably revolutionize technology, bringing a host of new digital applications, and ease our use of them. What might speed adoption is the fact that the media is difficult to copy -- not only would a would-be pirate have to have some high level of knowledge, but the technology required to create the cards doesn't come cheap.
