B&N has an Ipad app that allows you to access their entire ebook collection, the same collection that the Nook has access to. Since the Ipad is a more flexible computing device, there's a range of apps that provide access to other ebook stores, such as the Amazon, Apple, and Kobo ebook stores. The Ipad gives you access to more, but you may find yourself satisfied with the 2 million + ebooks available through Barnes & Noble.
The number you are searching for is 700,000.
