I've recently bought for the first time an DRM protected ebook, from Kobo. Never again will I make this mistake, it's just ridiculous that I can't download a simple PDF file and read it on any device I want using any software I want, without having to install a stupid, bloated app.

No, I don't want to notify people on FB or Twitter about books I'm reading. No, I don't want to see achievements. No, I don't need personal stats. No, I don't want to join a club. I just want to read the damn book I just bought!
