Sure. I'll load the rendered view of the site I'm working on and flip through tabs on that window. Typically this takes up a whole screen, and It'll resize frequently if I'm working on a responsive site.

Usually the code editor or IDE takes up a full screen, with it's file tree view or whatever even a full screen can be cramped.

The document inspector/developer tools almost dominate the other screen. If you're used to development in that tiny framed view below the browser, do yourself a favor and pull that sucker out; Get a real look at your rendered document and network profile while you're at it.

Any left over space trades between the terminal, gui file transfer, irc, music player (wait let's keep this work related ;), spec documents, email, code references, credentials manager, file management...

I really could load up three more screens just for a normal workflow. I can screenshot if there's interest.
