IE10 has a smaller chrome at the top than both Chrome, and Firefox. I hear you on the plugins though.

But that's because it puts the tabs and address bar on one line, which as GP says, has problems of its own.

IE10 only has a smaller chrome when windowed. When maximized, it has the same (within a couple px) top chrome, but combines tabs and nav into one, so the chrome is actually less useful. It's mind-boggling that MS shipped something with so little polish.
