Here's a quote from the PR at theLeakyCauldron.com:
Ranges of ebooks is pretty open to interpretation. I did not find other quotes, but I recall reading that she wanted the books on all Readers. I think she is aware of the lock-in problem and is trying to get around that.
I will bang the drum once more: lock-in is bad because it keeps independent or individual booksellers from cropping up. B&N sells for Nook... period. Amazon sells for Kindle... period. There's no cross-sales. And unless you want to sell DRM-free Kindle/Nook format (which publishers aren't allowing in general), you can't open a store to compete with Amazon or B&N. Very few people have "the goods" to challenge this model, and JKR is the one.
The only "hilarious" thing about lock-out would be the backlash against Apple/Amazon/B&N.
