Barnes & Noble Nook
Barnes & Noble late last year rolled up its sleeves and decided it wasn't going to let Amazon and Kindle gobble up the entire e-reader marketplace without a fight. As such came Kindle's most direct competitor, the Barnes & Noble Nook, an Android-based e-reader with built-in Wi-Fi, replaceable battery, SD slot and a few other features that took it beyond what the Kindle 2 had already. While Amazon, Barnes & Noble and the other titans of the e-reading world battle it out, however, it's platforms like Android that are winning: Android powers the devices and several of the e-book vendors have also made versions of their e-reading applications fit for Android devices.
