The problem with nanotech press releases is that they can be useful for attracting large piles of money, whether there's any actual product there or not. Over the last ten years, out of hundreds of press releases that said something would be ready in "several years", I can't think of any products that actually made it to market. (Including, and especially, from Stanford researchers.) When several groups confirm the results and talk intelligently about the engineering obstacles to scale-up, I'll pay attention to this one.
