Amazon Kindle 4

September 28, 2011

The fourth-generation Kindle was significantly less expensive (initially $79 ad supported, $109 no ads) and features a slight reduction in weight and size, with a reduced battery life and storage capacity, compared to the Kindle 3. It has a silver-grey bezel, 6-inch display, nine hard keys, a cursor pad, an on-screen rather than physical keyboard, a flash storage capacity of 2 GB, and an estimated one month battery life under ideal reading conditions.
