I'm at DEMO in San Diego and just saw the first really interesting presentation of the morning from a company called Plastic Logic. It's a document reader like the Kindle, but designed more for business documents, with a format like a regular 8.5-inch-by-11-inch piece of paper.

But the most interesting thing about the reader, which is supposed to be formally announced early next year, is that it's built on plastic instead of silicon and glass. That means it can bend or even be hit by the heel of a shoe, if you can believe the company's video, without any serious damage.
Like the Kindle and the Sony Reader, Plastic Logic's version is monochrome and easily read in broad daylight. It weighs less than a pound and has a battery life of days, according to the company.
You can markup a document using your finger on the screen or write a note with an on-screen keyboard.
The device looks very cool, but there were some warning signs about the demonstration: The product doesn't even have a set name yet, the company's factory won't open until later this month and the company gave no information during their presentation about the cost of the device. If Plastic Logic is able to actually deliver a device like this one, though, it could make a big difference in how people read documents.
