***But you can listen to music while doing something else. Try that with reading a book/magazine.
Tried it; liked it. In the car, in the house, at the beach. Audio books, as one example.
From what I understand, the "new" Ipad content will wind up with articles and clips that can be set to read/run like a slide show. Just give it a little time for folks to figure out how to do that and use the devices to view/hear "content" more and more. It's all about making it easy to get the "content" into your head. Apple is good at that - and your head turns out to have a lot of room!
Before that, even wired the house (20 years ago!) so a movie playing in one room could be watched all over the house, in the garage, and, on the patio at the same time. We went from finding no time to watch TV for 1 1/2 hours to buying more movies (a lot more) because we could clean house, cook, pay bills, brush our teeth, exercise, etc. and not be "butt stuck" to the couch.
There's really no reason a stream like audio books, movies, pictures and so forth won't be ported anywhere you want it to be around you. This is just one device and one way to get what everyone finds out they "need." Although, the guy walking down the sidewalk yesterday reading a book while listening to his iphone play music was a little hard to figure out. I mean, what's the retention rate when you're doing four things at once? Not that it matters, he'd bought all that stuff and the money was out of his bank and into someone else's.
I agree that this debate isn't about Apple vs. Amazon. It's about overhauling the paper-book publishing model from top to bottom. I too predict smaller publishing houses with authors and small editing groups doing Internet based marketing efforts instead of print, TV, and book-signing tours. The world changes; change can be a lot of hassle; but it's always gonna happen eventually. Just ask any dinosaur... Oh, wait...
