Kindle is Amazon's best-selling product ever

Amazon.com is reporting that in just five months, its third-generation Kindle e-book reader has replaced ‘Harry Potter and the Deathly Hallows’ (Book 7) as the best-selling product in the online retailer's history.

The company also says that on its peak day, November 29, customers ordered more than 13.7 million items worldwide across all product categories, which is a record-breaking 158 items per second.

“We're grateful to the millions of customers who have made the all-new Kindle the bestselling product in the history of Amazon - surpassing Harry Potter 7,” Amazon.com's founder and CEO Jeff Bezos said.

Bezos said that many of the people who are buying Kindles also own an LCD tablet and that customers report using their LCD tablets for games, movies, and web browsing and their Kindles for reading sessions.

"They report preferring Kindle for reading because it weighs less, eliminates battery anxiety with its month-long battery life, and has the advanced paper-like Pearl e-ink display that reduces eye-strain, doesn't interfere with sleep patterns at bedtime, and works outside in direct sunlight, an important consideration especially for vacation reading. Kindle's $139 price point is a key factor - it's low enough that people don't have to choose."
