I learned a new detail about Blio today and it has changed my opinion. Earlier this week Mike Cane asked me about Blio DRM on Twitter (Here is the site he linked to). I had thought that Blio used Adept DRM on its ebooks. On the off chance that I was wrong, I sent an email to the Blio website and asked them to clarify the DRM question.
Blio will not be using Adept. Instead it will use Microsoft PlayReady.
I will not tolerate a new DRM on a mainstream format. I'm going to make it one of my goals to kill this format as expeditiously as possible. Who's with me?
