Let me put it this way: Apple doesn’t seem to believe that Blu-ray will be a standard storage medium for computer users in the next decade or so like DVDs and CDs were before. That might be the reason why they are not exactly eager to ship their computers with a Blu-ray drive. That assessment rings true to me. I might buy a Blu-ray player for my TV but I don’t think I really need it for my laptop. (I might want to watch something on a Blu-ray disc but I’m actually kind of tired of all that physical media. I bought my last CD 18 months ago and my last DVD something like two years ago. I don’t really know how true that is for the rest of the world, though.)
