Input: I bought an original Kindle when they first came out and loved it. All the variations that followed didn't seem to offer enough new features to upgrade, so I stuck with mine. When I saw the features of the Paperwhite, I hesitantly decided to upgrade. I DEFINITELY made the right choice! I absolutely LOVE it! The built in light is great, the touchscreen is a lot better than the original keyboard, and I love how you can see how much time is left in the chapter/book that you're reading. Amazing product. If you're trying to decide if you should buy one, I HIGHLY recommend it.
Output:
Positive Review
