The new, sleeker Kindle may be a relatively minor upgrade compared to its predecessor, but it's making an impact where it counts the most: sales.
According to Amazon, the new Kindle has been selling faster than any of its previous iterations in its first four weeks of availability. Furthermore, the Kindle has been the bestselling (as well as the most gifted and most wished for) product in the same timeframe on Amazon.com and Amazon.co.uk combined.
The new Kindle has the same 6-inch reading area as its predecessor, but it's smaller and lighter. Screen contrast has been improved by 50%, and page turns are 20% faster. The battery life now lasts up to one month, and storage on the device has been increased to 4GB.
