Kindle DRM doesn't annoy me at all. I'm not annoyed by just the existence of some technology, I'm annoyed if this technology hurts my ability to do what I want to do. I do want to read books on iPad, iPhone, Mac, PC and Kindle. I'm able to. If I wanted to steal books I could have been annoyed, but I don't want to.
1984 demonstrated that your ability depends on the continued goodwill and competence of Amazon, who reserved for themselves the power to steal any of your Kindle store purchases.
