I am a writer and have been working on my book. I use the reader for pleasure reading a bit but it is mainly for my research and character information. It is very portable which makes it nice when I want to go out and about to work on my book.
It is also nice to have my book map for reference when I am out ( it previously hung on my wall by desk).

I have several different reference manuals etc that I use.

MailDroid is my fav email app. I use dropbox frequently. Fring - I am not too into though and would like to find a different app.
