Android Apps

Since I was having difficulty using iTunes, I've chosen Android Apps.

1) Book Reader Premium: A virtual bookshelf, similar to the nook and kindle, on a small screen. $2.99 plus the cost of  each e-book; there are plenty for free.
2) Nook for Android and Google Books: FREE! Better option than the Book Reader Premium because people are more familiar with Barnes & Noble and Google.
3) Wiki Encyclopedia and Dictionary.com: FREE! Great choices for that question that you know the answer to but cannot think of it.
That's what I have found so far.
