Either you are buying off a different Amazon store or there's some new Topaz DRM decryption scheme. As far as I know, most current Kindle books aren't crackable

  Hardly new... they're definitely crackable.

  I've had one Kindle book recently that Calibre wasn't able to crack automatically. It was a Kindle print replica textbook which I bought to read on my Touchpad in class. Turns out when they say "PC/Mac/iPad Compatible", they really mean ONLY PC/Mac/iPad. Android Kindle apps can't read them. I spent the entire weekend cracking their various obfuscation methods to find out it was a DRM'd PDF wrapped in a Palm Database format container. When I got it completely stripped, it was a straight PDF with no loss of functionality. Could they have sold it as a PDF with their normal Kindle DRM? Yes. Would this have been sufficient enough to keep piracy to acceptable levels? Yes. Any miniscule amount of DRM is enough. It's like putting WEP on your router. It will keep out the riff raff (which is good enough for most cases) but anyone who is determined to break your encryption will figure out how to do it. With something like an ebook, I would imagine that 9:1 sales to piracy rate would be realistic, and that's well within acceptable range in my opinion.
