First off, thank you for doing the WBGP. You're the only site that I've found that tests everything that I don't have time to test.
Second, I noticed a lot of comments noted how performance is so close between browsers that it's no longer important. I personally max out my PC's resources, and performance of every application I run is very important. Not to mention, as new technology is developed, more resources are needed, and better-performing applications are becoming more and more necessary.
Third, I agree with a lot of the comments about "what's really important" in a browser. I think it's hard to create a comparison about that, though, because users are so different. For example, I primarily use Chrome for several reasons - smart URL bar, easy menus, tab handling, built-in developer tools (don't need to install Firebug extension equivalent), and speed. At the same time, a lot of my developer colleagues prefer Firefox for the extensions they use. That makes it hard to say which browser would be "better to use."
Fourth, I think it would make sense to either do a separate WBGP that focuses specifically on real-world performance, or add something like that to the current WBGP. Every "normal user" cares about pages loading without flaws, stability, responsiveness, and usability. IE might load pages the fastest, but if you use a browser like my wife and leave 40+ tabs open in 3-4 windows at all times, IE doesn't load pages at all; it just crashes. Chrome can handle that kind of use without any issues (I'm assuming Firefox can too, now that they fixed the memory leaks, but we keep Chrome for other reasons).
Ok, sorry for the super-long post. Thanks for all your hard work in putting these articles out for us!
