I think all of you Bluray naysayers should realize, at the moment, that the majority of the computer using public either has a dial-up connection, or a slow connection, making downloading huge movie file impractical. Sure this can and will change in the (near) future, but it is not there yet for the masses. I don't want to have to buy new hard drives every time I fill one up with movies; it seems like a ridiculous proposition. And if i am storing everything only, where is the security? There is no network on this planet that is hacker proof/safe, while the CD/DVD/BD in it's case is relatively safe, be it from computer intruders, as well as, magnetism and other destructive forces. Why would I want to waste 50 gigs of hard drive space, when i can put it all on a disc and throw it into my desk, especially when hard drive space is more expensive than plastic media?
Some of you folks are not wrong that optical media will eventually become extinct to another form of portable media, but we are in the here and now... in the next ten years (give or take) this will most likely become the standard for movies (like DVDs have been for the last ten years), and physical longterm (potentially incorruptible) data storage. Maybe the next portable storage media watershed will yield something else, but that is no reason to not use the current technology to the fullest; it is here, and it will become relatively cheap in the coming years. I mean the cost of a blank CD-R when it was first released was more than $10 a disc, now you can get a spindle of 100 DVDs for $0.10 a disc. Apple should embrace the technology, especially since every other computer manufacture will, and this technology could be a deciding point for many people that are buying new computers.
Sorry for the wall of text (I could probably go on for hours here), but I feel that some of the ignorance (no offense), and short-sightedness of some of these folks is a little ridiculous; it's like saying I need a heart transplant now or I'll die, but I might as well wait until the technology is better (not that extreme, but I hope you get the point). Also, I would like to pose a question to the naysayers: How could the integration of new technology be a bad thing for Apple?
