A fantastically interesting piece, with an aspect of e-book buying I didn’t know before:
It is possible to unlock the DRM on a Kindle ebook and transcode it to epub format for use on other readers; but it’s non-trivial. (Not to mention being a breach of the Kindle terms and conditions of use. Because you don’t own an ebook; in their short-sighted eagerness to close loopholes the publishers tried to make ebooks more like software, where you merely buy a limited license to use the product, rather than actual ownership of an object.) So, because Amazon had shoved a subsidized Kindle reader or a free Kindle iPhone app into their hands, and they’d bought a handful of books using it, the majority of customers found themselves locked in to the platform they’d started out on. Want to move to another platform? That’s hard; you lose all the books you’ve already bought, because you can’t take them with you.
