Another tip (I don't think has shown up in the thread!) is that you can load the OverDrive app and then download mp3 and epub books through OverDrive via wireless.
The books are readable only on the LCD however.
Take a look at the site I maintain at the Library where I work. We do ebooks on lots of devices (through OverDrive). We have a pocket edge that we use to show off the Android app.
