It depends a lot on your screen size. Below ~19" I just keep everything maximized and use hotkeys to rapidly switch between windows. I'm usually flipping between a text editor and web browser. On even a rather large laptop, 50% of the screen width is too small for web pages. Unless you're doing data entry I doubt you're memorizing the contents of one window to input it in another, and if you're doing that copy/paste exists.
