Barnes & Noble’s two new tablets want to help you find your next book

Barnes & Noble’s two new Android Wi-Fi tablets, the 7-inch Nook HD and 9-inch Nook HD+, aim to compete with other moderately priced tablets such as Amazon’s Kindle Fire and Google’s Nexus 7. But the new Nook tablets, starting at $199 and available in October, differentiate themselves most from competitors when it comes to some new reading and discoverability features. The company is introducing “Nook Channels,” curated collections of books that “speak to a certain type of reading or a certain type of content.”
