Although I have read the threads on using Android devices as an eBook reader, I am unable to get a clear picture of what's available. I generally buy eBooks from Sony's store, which at least sometimes delivers epub files. These must be encoded as restricted though, because neither of the two eReaders I installed on my NexusOne would recognize the Sony files (though they worked on free books available). So I wonder whether there is any reader I can install that will allow me to view purchased books from Sony; I'm not trying to pirate anything here, as I've paid for the books, just frustrated that I can't read them on Nexus One. Maybe the answer is to stop buying from Sony and purchase from Barns & Noble instead, which appears to have an Android reader available for download, but I'm not sure whether that will work even on B&N books, and I'd like to stick with Sony. Any suggestions are welcome.
