If you find things on your office desk and can tell when they were from by the stacks of paper you found them in, Sony’s Digital Paper would like to help out. The handheld letter-size device lets you annotate, share, and save all the documents you and your coworkers are working on. The 13.3″ display shows full-page docs in PDF and then allows you to use the stylus to write and erase on them. Sony claims you will get around three weeks on a single charge and that you can store around 2,800 PDF files on the 4 GB of memory (you can also insert a micro SD for added storage). While it could come in handy for those who are overwhelmed by documents strewn across their desk, the price tag might make it a difficult sell to the average consumer.
