The A500 is preloaded with Google Books, which is nice because they have a great selection of free books--I read a lot of old books in English, so that works well. Now, I know these books are just page scans, so you can't treat them as text. But it would still be nice to be able to annotate them--mark them with a stylus, post sticky notes, etc. Google Books doesn't let you do that, from what I can tell. Is there software that (1) lets you do that, and (2) can be used to access Google Books? (I'm not even sure where the books I've downloaded are on my drive--I have a bunch of them saved for offline reading, but haven't been able to locate the files.)
