Kindle moniker to remember? Here it comes! "Kindle Keyboard." That's the name that was bestowed upon the tried-and-true 6-incher today after Bezos unwrapped a touchscreen model and a low-cost variant that tout no physical QWERTY keys whatsoever. Now, the WiFi-only Kindle is going for as low as $99 with ads (down from $114), while the non-ads edition can be had for $139. Meanwhile, the 3G + WiFi Special Offers edition has fallen from $164 to $139, and the ad-free brother is going for $189. Naturally, all four of 'em are in stock and shipping today if the new blood just didn't do much for ya.
