And your point is?
Google and Amazon sell their tablets at these prices and probably with a loss because they expect to generate revenue through their content supply chain. That's a business model that is not alien to Apple; after all, they've also sold subsidized products in the past (like the original iPhone) and many of those billions that they have in the bank were made through the iTunes store and Apple's 30% tax on everything that's being sold in it.
My point is not that they
couldn't go to such a subsidized business model. My point is simply that every time these iSupply threads show up, there are always people who complain that "here we go, this right here is PROOF that Apple is ripping us off!" without taking into consideration all of the other costs involved but not listed.
On the whole though I think you are right, and I think we're starting to hit the point where either the Apple Tax is simply too high now. I don't know if it's because perceived "greed" from Apple is higher than ever (especially in light of all these patent lawsuits, highest share prices and profit reports ever, obvious marketing decisions like not letting iPhone 4 users get Siri, the Google Maps fiasco, etc.) or simply because, hey, the competition ain't so bad now and it sure looks like other companies have figured out how to produce very capable products at lower prices.
Personally, I'm starting to wonder if my next phone won't be an Android. From what I can tell, it will play nice with my iTunes library, even Airplay to my Apple TV, let me have the best of all the apps I'll need, ... and it'll be much cheaper.
