You can argue with those or other sources all you want, but if you really believe Blu-ray is going to outlive digital downloads, I just have a couple questions:
Where can I buy "Transformers 2: Revenge of the Fallen" on Betamax?

Where can I get a copy of Windows 7 or Mac OS X 10.6 on 5 1/4" floppy disks?
Who is giving up current tech for tomorrow tech?
Why do you put words on my mouth? When did I said blu-ray is going to outlive digital downloads? I said blu-ray will still crown king in the near future, of course download is the future when the infrastructure catches up, but right now not all people enjoys high speed internet, that is why physical media is a must for a lot of people.
Your argument on betamax is not working too, first of all, VCR wins against against betamax. Yes, you have to pay if you want to buy the dvd version of the movie, then pay again for the blu-ray version. Think about this way, today you buy the 720p version of the movie on itunes, do you think you don't have to pay again when apple upgrade its quality to 1080p in the future?
Who is giving up current tech for tomorrow tech? You cannot be serious so i am going to ignore that one.
They're not giving up Blu-ray, because they never had it.
Did it ever occur to you that perhaps Apple isn't interested in marketing to those people? You can't use an iPhone without a cellular account and iTunes is geared toward those who have credit cards. There is a market segment that Apple isn't trying to reach, intentionally.
Perhaps because they want to be seen as leading and not following.
It amuses me to see so many criticize Apple for not being smart because they don't do what some poster in a forum thinks they should do. Their bottom line indicates they're not doing too shabby with the decisions they've made, even though some may disagree with their decisions.
Then its not a very smart decision for Apple, i for one will never buy anything online, how can one buy a product before examine the product with their eyes first is just beyond me. and don't know how reliable this source is, but if Apple really isn't going after those people who doesn't have an internet access, they are giving up a lot of potential market share and therefore not very smart, its simply their lost and i dont see how amusing it can be.

United States : Internet Penetration Rate 77.30%
This is only about using internet, and how many of them are actually using high speed internet that it can support streaming media?
Leading themselves out of the market, sure. (spelling mistake)
Of course a company should produce what consumer wants, its call supply and demand, thats why a company exists. Imagine BMW only produce electric car and tells you that you dont need gasoline engine, ignoring the fact that the infrastructure doesn't catch up yet.
