Thanks for asking that question, Natescape! I have Sony Reader software on my computer and thought I would get it for my eDGe, too, instead of going through Calibre or emailing books to myself. I couldn't find an easy way to download and gave up.
You might want to read the whole thread that Emusan pulled the dowload link from. It looks like there are some "issues" with the Reader on Android (maybe fixed by now?):

I wonder whether books downloaded to the Sony software will be readable on the e-ink side. Does anyone know? Perhaps I'll just try it myself and see.
Emusan, you rock at finding information! Keep up the good work!!
