DRM is not just an inconvenience...it is often a violation of your rights. There are plenty of things that you are allowed to do under fair use that you cannot do with something locked down under DRM. Some of the more common things you might want to do are given to you as workarounds (you can always re-download your music from iTunes to a new Apple device so you don't need to make a backup copy) but not everything. For example, is it legal for you to back up a DVD that you buy in case your kids use it for a frisbee? Who can tell? Can I buy a DVD in France and play it on my DVD player in Texas? Not without resetting region codes or hacking. Can you make copies of sections of a book you read through Amazon on your Kindle or iPad for a study group in your school or synagogue? Not easily (perhaps not at all) though that is apparently allowed under copyright law. Can you move your books from a Kindle to a Nook to a future device for reference in the future? Who knows?

My point is, it is not just that they are treating us like criminals with the DRM, it is that they are also restricting our fair use of the music/books/movies/shows that we pay for. We end up either unable to do things we could do with non-DRM'ed technology (like paper books or CDs) or we end up paying for the same content multiple times.

All that said, I am a huge hypocrite because I own an Amazon Kindle which is a pretty solidly locked-down-with-DRM device (and I love the thing). And I bought a whole bunch of crap on CD's in 1988 that I already had on tape or vinyl. (Which also makes me kind of an idiot. And old.)
