I wonder if he has the same issues with the latest platform preview (which came out nearly two months ago).
Now, all this fairness aside, I'm extremely curious why MS isn't adopting the rapid release cycles that the Chrome team have used. As a (potential) consumer of the Internet Explorer line of products, I feel like I'm left out in the cold when I see that the last release was sometime last September. In the meantime, Chrome has added a major enhancement to their JavaScript engine, WebGL support, and more. More importantly, they've added this stuff incrementally so I, the (current) user of Chrome don't have to wait for months for the next major release.
Or perhaps more to the point, I'm curious why the IE9 marketing team don't see the promotional advantages of rapid releases as compared to the old major release model. As the Chrome team have said...market features, not releases.
