I just got my first ebook with drm and I already hate it. I downloaded the book, but it's just an xml-like #acsm #adobedigitaleditions file.

I know that there are some "options" for calibre. And being on linux they are probably my only options. But the abyss of this #DRM shit is overwhelming.
Do I have an adobe ID from the book shop?
Do I have to create my own one?
If I get the epub from the acsm, will this book forever be connected to this ID?

What a bummer...
