I've begun to use Chrome exclusively when I'm in the PC environment. Much better than Firefox. I've never liked Firefox (gasp!), it strikes me as heavy and clumsy. Chrome is anything but.
Depending on the quality of the Mac port, it will probably replace Safari as my main browser. Until Safari 4, unless V8 gets faster than SquirrelFish or they switch Chrome to SquirrelFish.
Man, browsers are sure moving fast these days. I love it
