We do a lot of research everyday to make sure we are aware of how the world is shaping up according to our own predictions and I think browsers are becoming an important part of how the future of us as users will interact with the internet.

In the past we only had a couple/few choices, which to be honest is all you want if you're doing web development, but now with a lot of standards being adhered to and the core engines being used in other products, it is becoming less of a problem.

The upside is we all get more choice with out the hassle of sites not looking how the creators visualised them. Basically a page is presented properly without to much interference from of a badly coded browser (aka the old days).

Personally I think its an important step as a release, but will not become fully usable untill we start interacting with our screens with out the mouse. When we use multi-touch screens and OLED technology becomes more widespread, this type of experience will become part of the type of applications we use and build.

I only have to say iPhone and that hint of the future is obvious, the WOW factor is really our frustrations of us all being trapped in the same usability for such a long time.
