Totally revamped the first post. I took out many "not reviewed yet" lines by eliminating the "pros" and "cons" sections.
I split up the clients into sections to make them easier to find. Big booksellers' apps (Barnes & Noble, Amazon, Borders) are in their own section. There is also a section on apps that specialize in Chinese, Japanese, or Korean script. I also added a few comic/manga readers and a section on Android tools for working with eBooks.
