I installed Google Chrome, Google's new browser. My first impression is that it's very plain. I don't expect this to take off in large numbers, because I think most web surfers will want more features than it currently offers.
As far as web site support, I tried CFQuickDocs, and everything worked fine. I was expecting parts of the site to be nonfunctional, because Google wrote a new JS engine (dubbed V8) from the ground up, but everything works fine. I also tried Gmail, and holy crap it's fast! In Firefox on my machine, Gmail takes from 5-15 seconds to load. In Chrome, it loaded in about 1 second!
