Send e-books to your Kindle using Calibre
Last night I needed to transfer an EPUB file to Eliza’s Kindle from my Mac. It turns out that Kindles no likey the EPUBs. (I didn’t know this, I’ve never really used one.) So, after a bit of searching I found Calibre that, while it doesn’t have the best looking UI, is sort of the Swiss Army knife of e-book management.
