"New spray-on, nanotech coatings could keep iPod screens from scratching, make paper products waterproof and perform other minor modern miracles. And because they are cheaper, easier to apply and more environmentally friendly than substances currently in use, nanotechnology-based coatings could replace many of today's industrial paints and coatings. The nano coatings, "liquid solids" composed of extremely tiny particles, possess unique characteristics -- like extreme flexibility, easy adhesion and resistance to corrosion and microbial growth -- that could profoundly change the manufacturing process."Potentially a beneficial and significant upgrade for every device with a screen, and one that I'd welcome. My single biggest complaint about my Zen Vision:M is that the screen had scratches in it two days after I bought it, and I was extremely careful with it. The same problem occurs with Smartphones, Poket PCs, laptops, and many other devices. Bring on the nanotech!
