With half a million Kindles sold since 2008, Amazon has decided to update their e-book-reading wonder with the Kindle2, featuring slimmer specs, more wow factor, and a free Stephen King novella, UR, about the horrors of technology (that’s “You Are” for non-texters). A new application, Read to Me, speaks any content on the device back to you in a computerized voice. Add to that seven times more storage, 20 percent faster page-turning ability, 25 percent longer battery life, a new five-way joystick for navigation, and Whispersync bookmarking, which lets you bookmark your page on one Kindle and pick up where you left off on another. $395.
