I used it for about 10 minutes yesterday for the first time. Like everything Google does, it has a very clean UI - which I love. The fact that each tab runs in it's own process is genious. I personally use Avant Browser and swear by it, but many times while one page is loading and I try clicking on another tab, the program freezes up and I have to wait.
The first page I loaded with Chrome was
www.foxnews.com and it was noticeably slower than any other time I've loaded it. It could be my Sprint card happened to choke just at that second...I guess I'll have to test it a little more.
Like I said about Android, everything Google does is awesome, and I'm sure in a few months once the kinks are ironed out, it will be the best browser out there for simple web browsing. FF will always be king if you need every add-on imaginable.
