Save the Trees

Plastic Logic in early 2009 will release what may be the first real, usable version of electronic paper. Check it out here. The upsides are numerous, including not having to carry tons of books around and not having to print, distribute and trash billions of newspaper pages a day (world-wide), decreasing the demand for paper and therefore the number of trees that need to be cut down to supply this demand. It's compatible with a wide range of document formats (PDF included) so this may turn out to be a very viable product.
