A:
When I looked for an ereader to install on my ASUS Phonepad this was the first app which I tried and since then I didn't try anything else. I installed it on my PC as well. What I like about it is its easy to use interface and the fact that it recognized all my e-books. At first I was unhappy that I couldn't read my PDF books in it  but then I installed the PDF plug-in and now I use this app for all my books.
