Interesting. I just checked on the Android Google Market and found several of the books I was considering were just $5. They are in multi-file HTML format inside the APK, so this is even cheaper and given I wanted them on the Android phone/tablet anyway, easier. Even better the eBook app O'Reilly delivers has an "Export to ePub" button that will send it to an ePub on your sdcard.
