will be interesting to see how it works on your travels too. I've seen the screen's and they are amazing. I'd jump on one if book publishers offered dual format. I mean I love owning books. I prefer to read them. I love having them on the shelf but would rather be able to carry lots around all the time. Like Blu-rays come with DVDs in some cases it would be great if you could own the book but for say 50p or a £1 more you go the digital rights too. Sounds like win win to me.
Cases - if i'd been paying attention I'd have shouted play or somewhere like that I found my found case well cheap there.
