Me, too, and it is much faster but I have some firefox extensions that I need, and after running awhile Safari seems to hog resources (worse than firefox) and conflict with my graphics program so I'm back to the stable firefox 3 release. I've tried the beta too and will switch when my add-ons are updated.
Haven't tried chrome. Seems like it won't do what firefox does either even if it is fast. Building browsers without add-on capability (just about any program, actually) seem very dumb and limiting IMO.
Not only that, but if you are using windows(which I assume you are) and you use Netflix instant viewing capability, Netflix doesn't recognize Safari except on Apple machines. Won't allow you to watch movies on Safari if you are using windows, so I went back(actually never really left)to Firefox, which I have never had any problems with.
Google Chrome hogs resources too. I used it for about a month and I never noticed it was any faster than any of the other browsers I’ve used.
