Sir, you forgot to mention Amazon's forays into mobile, non-PC devices. Right now, in the US, Europe, and in Japan using Imode devices, customers are getting recommendations, doing price comparisons, and purchasing items using Amazon's 1-click technology via mobile devices.
A majority of the concepts you state in your article have been exposed for customers to use via traditionally non-connected devices.
Even merchants who benefit from Amazon.com's 3rd Party HTML platform now have the ability to sell their items via mobile devices, specifically cell phones, without having to learn any new mark-up languages.
Amazon.com is ahead of the curve and has been embracing this X Internet type of experience for years.
I think http://amazon.com/anywhere contains data on how you can learn more about the X Internet and Amazon's forays into this space.
