As my original post said this all applies to webapplications. If you're building a consumer facing brochure site then you neither want nor need most of these new web features.

Have you actually used or tried to deploy ChromeFrame? Its plenty ready for prime time, and features:

1. A 60sec installation

2. No browser restart required

3. No admin rights necessary

4. IE6+

5. Autoupdate just like regular chrome

Even the most technophobic user can follow 2 links to be able to use an app they really want to use.

And remember this is all about applications, not your average brochure site.

What proportion of web applications are funded by large companies? Obviously in terms of actual users, there's always going to be far more consumers than corporate users, but in terms of dollars-per-user? Any large company will have a large number of internal, normally web based, tools for all sorts of things - training, asset management, expenses, travel booking - and the amount of money that the company will pay for these tools will always be higher on a per-user basis than either adverts or consumer payments would bring in. Certainly sites with almost no broad corporate use - social networks and the like - will have fairly insignificant IE use, but corporate facing web applications will see broad IE use.

ChromeFrame is great, but it is probably against the usage policies of a lot of companies. Even if it isn't, most people are fairly wary of installing something on their company machine. You'd need the IT department on side to get broad deployment.

I'll admit, I haven't. That feature list is mighty impressive and all kinds of commendable.

That said, it still fundamentally is requiring people to install something on their machine. This is a difficult thing to do with the uneducated and often outright forbidden in the corporate world, so the two key demographics here are also the two least likely to use ChromeFrame.
