Barnes & Noble said Wednesday that its new Nook HD will come in two sizes, one with a 7-inch screen (measured diagonally), starting at $199, and one with a new 9-inch diagonal screen, called the Nook HD+, starting at $269.
In addition to the new HD screen and a lighter body, Barnes & Noble is adding a video purchase and rental service.
The company is seeking to offset tough competition from online retailers such as Amazon.com, as consumers increasingly move away from traditional books and DVDs to electronic books and streaming video.
