Epubor - Great software, easy to use.
Thus far Epubor is looking to be extremely useful. I have numerous kindle e-reader books that I'd like to move to Calibre, but as always DRM is stopping me. Epubor can allow me to remove that DRM, and is the only tool I've found that actually works on the new encryption for Kindle books. Of course, the free trial vs the $25 price tag is a bit annoying, and normally would result in me bumping this down to 3 stars at best. However, Epubor's dev team has come up with an ingenius solution to those of us who don't wish to pay - free licenses for reviewing and rating their software. I actually intend to inform several of my coworkers about it, and if/when I get my full version, I'll re-review it to see if it gets a 5 star as I'm hoping it will.
