Honestly, I can’t wait until something like this comes along that people could actually afford.  At over $5000, I don’t see this in every household yet, but nonetheless it is a definite step in the right direction.  The Prepeat printer uses a sort of thermal paper that is erasable and reusable up to 1000 times.  This is the sort of step that makes flash drives so much more useful than CD-R’s.  People could print something for reference, and instead of tossing it in the garbage, reuse the paper later.  Good stuff…but definitely a look not to today, but the future.
