I rant into an issue yesterday that makes the kindle fire better than the first world problem imo.
I rented some textbooks online through amazon, but one was only on b&n. so i sideloaded the nook app on the fire (surprisingly easy), and rented it from b&n. turns out you can only view nook textbooks on nookstudy which is only available on PC and Mac desktop.
I have never had this issue with amazon and their kindle or kindle app. geesh. Who would actually want a portable textbook? #sarcasm#
