I haven't tried downloading from amazon with it yet... I download alot of books from
Project Gutenberg Lots of great free ebooks there.
I have used mobi, epub, pdf, and text formats so far and they all work...
I believe the amazon kindle uses the mobi so I would think they would work fine..
A hint of something I figured out.. If you like to try and keep your files more organized on the blip I started by adding a folder called books then I added my downloaded ebooks in there. I was also able to put other folders of collections of books or series into the books folder. That way I only have one folder that shows in the main pages.
