When it comes to the Amazon Kindle, you don’t necessarily have to buy the e-reader hardware in order to enjoy its library. There are all sorts of free mobile apps. The same thing is expanding with Barnes & Noble too with the introduction of the nook for Android app. As you can probably figure out, this Google Android app will grant you access to just about everything that the Barnes & Noble nook has to offer. You’ll need to have Android 1.6 or higher, but it means that you can shop for over a million titles including new releases and free eBooks.
