These are devices that let you store books on them, and you read them electronically. It's a portable device that is conveniently sized, like a regular sized novel would be. It is meant to be convenient and save paper. The most popular one out now is Amazon's Kindle. The Reader from Sony is the next most popular such device. And there are others in the works by other companies such as iRex and Plastic Logic. Barnes and Noble has just released their version of the Electronic Reader today, and hope that it will provide some features that competitors can not.
Some cons to these new electronic readers include price. Both Amazon's new version of the Kindle and Barnes and Noble's recently released version cost $259, which does not include whatever books you would like to download to the device.
So, which one to buy? Well, Barnes and Noble has an agreement with Google to have free access to about 500,000 books that Google has scanned from university libraries. These free downloadable books are NOT available for free on Amazon's Kindle.
Although the market for these devices is small now, many say that the Electronic Reader will eventually replace the paper book all together. The convenience it has and the resources that it saves are two great reasons why the Electronic Reader may become the way we will always read in the future.
