I'm with David on this -- I wish I understood more about the DRM on the Kindle. I've been trying to find out for weeks, for example, what the story is with the "DRM-free" option for Kindle means -- is there a patent or contractual term that prohibits owners of Kindle DRM-free books from moving them to competing devices, or patents or other claims that prevents competitors from creating readers or converters for these books?
And, what, exactly, what the mechanism by which Amazon removes the "read-aloud" feature to comply with requests from the Authors Guild's members? Is that a firmware update to the device? A flag in the file-format? If the former, can users refuse the updates? If the latter, what other flags are there, and does buying a DRM-free Kindle file mean that they can't be switched on for you?
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
