I guess that given its android I would not be limited to kindle books (and DRM free books) but could buy/rent books from other sources.
If you have DRM encumbered files obviously you're going to need to do something else, first, but why did you buy a book with DRM? Seems unwise to begin with lol
Can you imagine buying a dead tree book and have the publisher come up and say "no no no, you can't sell that when you're done!"
DRM'd ebooks. What a world.
