Plastic Logic's eBook Reader

Here is a light, flexible, and strong e-book reader designed for business workers to avoid having to carry papers and books everywhere with them. The product also features some inking capability (a limited ability to mark up documents).

One of the problems with the technology will be the time and effort required to scan the documents electronically to carry them with you. Although, this can be avoided if the documents are printed to PDF instead paper to begin with.
