Kindle update adds Facebook and Twitter interaction, password protection, and better PDF control

Not to be outdone by Nook, Amazon has released the Kindle 2.5 firmware. The new software adds a number of interesting features including the ability to share passages of books with your Facebook and Twitter friends providing that, unlike mine, yours are literate (don’t worry, they won’t be able to read this).

The firmware will launch later next month and includes the following features:

The 2.5 software update for Kindle and Kindle DX is coming soon. We are rolling out the new software update to a limited group of Kindle users and plan a broad release in late May 2010. Check back here for updates on the release schedule.

Here’s a list of the coming enhancements:

Collections: Organize your books and documents into one or more collections.

PDF Pan and Zoom: Zoom into PDFs and pan around to easily view small print and detailed tables or graphics.

Password Protection: Password protect your Kindle when you’re not using it.

More Fonts & Improved Clarity: Enjoy two new larger font sizes and sharper fonts for an even more comfortable reading experience.

Facebook & Twitter Posts: Share book passages with friends on Facebook and Twitter directly from your Kindle.

Popular Highlights: See what the Kindle community thinks are the most interesting passages in the books you’re reading.

If you’ve ever tried to use PDFs on the Kindle, for example, you’ll notice the font is static and you can barely read most of them. Pan and Zoom should improve that as will the increase in number of fonts.

Incidentally, first generation Kindle users are SOL. The update won’t work for them.
