I use Chrome as my secondary browser. I find bookmarking site counter-intuitive (probably my fault) and, as much as I hate to admit it, I kind of miss the functions toolbar (File | Edit | View | Etc.)
With Firefox having become so buggy, and such a resource whore, I find myself using Chrome more and more often. I used to flip over to Opera, but, my last three viruses came through Opera and it’s making me gun shy to use it for anything other than compatibility testing.
What do you think? Have you used it? What’s your browser of preference, and why?
