Kindle Upgrade

Seems the 2.5 Kindle Firmware upgrade includes the ability to Tweet book passages on Facebook. "Other new features of Kindle 2.5 include password protection as well as the ability to categorize a book library into collections. Amazon also claims improved clarity and readability with two new font sizes. Staying with the social networking bandwagon theme, they've also provided functionality that highlights the e-book passages considered to be the most interesting by the Kindle community."
