I don't agree with it. Chrome is awesome, granted, but it's tightly designed for making Google more money. Not that it's something wrong with it, but it's not useful from my perspective (that might or might not be correct).

Let me explain you. When you type something in Chrome's search bar, you are searching. Firefox, having two bars lets you do different things. On the right one, you search. On the address bar, it lets you find. When I know I want to go to a wikipedia entry for, say, webkit, I don't have to look at the results. Go ahead, type "wiki webkit" on your Firefox's address bar* and you won't have to go through Google as it has the "I'm feeling lucky" behavior.

You can't do that on Chrome. I think that's the reason both Firefox and Safari are sticking with two bars.

*Note: It might or might not work. Each time I install Firefox I have to set the keyword.URL setting to "http://www.google.com/search?btnI=&q= because it stopped working, but that was the old behavior.
