The breadth of technology at Nook is huge, encompassing ecommerce, native apps, mobile apps, big data, and hardware devices. We are using the latest, like Hadoop for map reduce, and angular.js for 2 way data binding, and of course agile, daily scrums and stand ups. Our device is superior, with longer battery life, lighter weight, faster startup, and has the best resolution of any 7 inch tablet on the market. We also have an education division working with publishers to make college textbooks available in electronic form.
