On the lack of BD drives in the new Mac notebooks, quoth Jobs:
Blu-ray is a bag of hurt. I don't mean from the consumer point of view. It's great to watch movies, but the licensing is so complex. We're waiting until things settle down, and waiting until Blu-ray takes off before we burden our customers with the cost of licensing.
Takeaway? Huge battery drain, likely replaced by digital downloads in the not-too-distant future, so we'll hold off on the big price jump, thanks. Me? I still love 'em on my PS3, but I'm going to have to start using "bag of hurt" way more often.
