I prefer Fx as well, but everywhere that I see someone trying Chrome I make it a point to mention Iron.
Currently, I have Fx 3.1 b1 installed as it is a lot faster than 3.0.x and (on my machine) a lot more stable. And, as soon as Adobe finally releases Flash player (and, hopefully, Shockwave player) for x64 browsers, I am making the move to all x64 browsers.
