I'm planning to get a 2016 Paperwhite soon, it's my first e-reader ever. I've read that you can use Calibre to convert epubs to the kindle's format, however I'm afraid that the formatting in the epub book (spacing, content pages, etc) will be ruined/screwed up. I've read quite a number of books that had their words spaced out weirdly and formats a little wonky, presumably due to bad conversion. Wondering if that will be the same on Calibre, or am I better off buying books on Amazon instead? I have tons of epub books on my computer so I'm hoping that they can be read on the kindle, too.
