Here we'll show you how to save yourself the hassle of resurrecting your digital library by backing up your purchases to your computer, explain what digital rights measures Amazon has in place, and reveal how even those without a wireless network can save money by buying a Wi-Fi-only Kindle. The process is free, but it can be time-consuming. The trouble is, if anything catastrophic should happen, you'd be forced to download them all again - unless you have a backup. Amazon's Whispernet service does a very good job of delivering books directly to any registered Kindle.
