So.... thoughts on the new Apple iBook publisher? It looks like it works very well (I've not actually used it myself) but my big concern is that I've heard that in the terms of use the author basically signs all rights to their material over to Apple. And, I've also heard it is up to Apple as to whether or not they choose to publish your book, so if you've put a lot of work into something (e.g. writing and formatting your e-book) you can export your data but all your formatting (etc) will be lost.
I'd love to hear what others think about this. It looks like a neat thing to use, but I do have big concerns about the IP aspect of things.
