Amazon is eliminating users' ability to download Kindle books without WiFi, meaning you’ll want to move your library as soon as possible.

If you're an avid e-book reader or someone who has an extensive library of Kindle content, now is the time to back up your books: Amazon is killing the option to save e-books to your computer.

Amazon is discontinuing a feature that lets you download your purchased eBooks to your computer and transfer them to your Kindle via a USB connection. Although few people take advantage of this, it still awful that we're losing one of the ways we can download our content.
