What you give up by switching

Calibre manages books you already own in open formats. It cannot buy from the Kindle store, and books with Amazon's copy protection may not open there, so check what you own before you commit.

How to move

Fill your library from DRM-free sources such as Standard Ebooks and Project Gutenberg, and read on any e-reader that takes EPUB.
