The typical web browser UI is a terrible waste of pixels. It might be a requirement for non-techies but no-one surely clicks the back button or drags the scroll bar, at least no power user does.

I personally use Firefox + vimperator with menu bar, address bar and scroll bars disabled. A single line status bar has all the info I need.

I've also dabbled with some of the "micro browsers" but none was satisfactory without a lot of trouble configuring proxies, etc.

For the future, I am hoping that someone will put together a Servo based micro browser with a keyboard oriented user interface.
