The Robotic Book Scanner from Qidenus uses a series of technology to automatically turn the pages of a book and scan its contents into digital media. The product is currently used mainly by large university libraries, book archives, and companies, but lower-end products will soon come to market that will make the technology more accessible.

I love the idea of this technology, especially since it preserves the integrity of the original books. Now imagine having one in your home so you can load up your hard copies on your Kindle or iPad? That technology is not quite ready for prime time and likely will take a bit of licensing of hardware, software and copyrights before it is, but I look forward to it.
