Again, the numbers are against you. History has no meaning in this case, since the uptake of Blu-ray is quite spectacular, especially considering it had to first defeat HD-DVD (which as in any media format war, can diminish the initial uptake of a technology).
Blu-ray has more penetration than even DVD had at this point in its history.
End of story. Your only basis is Steve's comment.
Rest of your post is unsupported by current sales figures of Blu-ray unfortunately.
As for this last comment, Linux has been doing it for years. Of course, you could also install Linux over the Internet or a local network back in the 90s. Apple is kind of late to the game on this...
Though I don't see them selling you Flash media with an OS on it. Costs are prohibitive. They would just sell you a download you copy to a flash media you already have, like the Linux distributions do. Makes much more economic sense.
I have to disagree.
The argument is whether there NEEDS to be a form of physical media...we may not be there yet, but I'm pretty sure Microsoft AND Apple have both stated they believe the future is with Direct Download and/or NOT with Blu-Ray.
Netflix and Blockbuster would agree.
As to how they deliver an OS........they'll probably start with offering the new form with the old, track the progress towards phasing out OLD technology (yes, even Blu-Ray is old at this point), and making an informed decision from there.
I may pick up an iMac if its more of an update than just SB and TB (like they did with the MBP)...please!
