The Nook Tablet weighs 14.1 ounces and has a battery life of nine hours of video watching and 11 hours of reading.
The device will be available on Nov. 17.
The bookseller is also releasing updated versions of the NookColor and Nook Simple Touch for lower prices. The NookColor will be priced at $199 while the Nook Simple Touch is $99.
Current NookColor owners will receive a software upgrade before the holidays, which will add some of the functionality of the new Nook Tablet. B&N says the Nook Simple Touch will also receive a software update to make the type sharper, boost the life of the battery and enable faster page-turns.
