I'm already doing this with Opera, and I think Opera has it figured out a bit better, too. The curious thing here is, I guess, that I not only don't have an Apple Cinema display, I don't have a wide-screen display at all, and I even pivot my monitor by 90 degrees (the one I browse the web on.) I've made the experience that having a tall browser window is much more useful than having a wide browser window.

I like the big pictures on the tab buttons — gives me a visual idea of what I'm clicking on. I also like the tab stacks Opera implemented a while ago, even though I still have a couple of peeves with 'em.

One thing he's totally right about, though: address bars are largely wasted screen space. I'd like to only see them on newly opened tabs or so…

The address bar is the only security indicator you have in the browser. Hiding it to the extent you're suggesting leaves you pretty much defenseless against phishing attacks.

One could imagine some sort of indicator on the tabs. Or some sort of indicator around input/form fields, etc.
