The new device, which is still dubbed Kindle, has twice as much memory as its predecessor, which should make it a bit faster in operation.
Amazon says its design is slightly thinner (0.36" compared to 0.40"), lighter (5.7 oz versus 6.7 oz), and more rounded, and that it’ll be available in white in addition to its usual black. Bluetooth audio support has been added as well.
The device is available today, and retains the previous Kindle’s $80 price tag.
The battery, software, and 6-inch e-ink display at the heart of the device don't appear to have undergone any significant changes, so this looks like an iterative update more than anything else. If you have a higher-end Kindle Paperwhite, Voyage, Oasis, or even just a previous Kindle, there shouldn't be any need to switch. Nevertheless, if you’re in the market for a new, affordable e-reader, the speed boost should be appreciated.
