+## Going paperless?

+I _love_ my Kindle. It's light-weight, has a battery that lasts for about 4 weeks (I read about 1 hour a day), and it features a quality e-ink screen. The 3G options is fantastic, as you can leave your Kindle always connected and use services like [Readability](https://www.readability.com/) to send web pages neatly 
+formatted to your Kindle for later reading. 
+
+Most of the books above are available in Kindle format as well. So if you're not already paperless, 
+why not start now?
