The new Paperwhite looks the same as the old model, but features an upgraded screen, a faster processor and some new features designed to make reading more social and enjoyable.
The new device has an upgraded screen with (naturally) 'whiter' whites and 'blacker' blacks.
The built-in light also gains an upgrade, and is able to guide the light "toward the surface of the display so you can read comfortably without eyestrain".
The processor gains a 25% bump to increase page turning speeds, while the touch sensitivity is also improved.
'Page Flip' is a new mode designed to let you flip through your book without losing your place, while improved vocabulary, lookup and social reading features also look set to improve the E-reading experience.
In a hands-on preview, Time magazine said:
"[We] don't think owners of the current-generation model will be crushed to learn they're about to become owners of previous-generation Paperwhites. The new features aren't that enticing. Mostly, I'm happy that the e-reader category remains popular enough that Amazon is still updating the Kindle as briskly as it ever did."
The new device will be released on 30 September.
