I'm looking into the Amazon Fire and The Barns & Noble Nook tablets. The nook looks like it's the one to get. After all, it does have twice the amount of RAM and hard drive space with an expandable memory slot. It also has a better battery life. And all of that is definitively worth an extra $50. However, before I make a final choice, I was wondering if the Nook, also and Android tablet, has all of Android's marketplace apps. The website does not get into that very much. Even though it is an Android tablet, you never know. Thanks!!!
