Aren't you tired of needing to resize Safari (or other browsers) to the maximum size everytime you open a new wondow? Well, I found this script. Have it as your Home Page and it'll zoom the window for you.
javascript:window.resizeTo((screen.width-150),(screen.height-50));window.moveTo(0,0)[robg adds: I'm not sure I understand the need to zoom every browser window to full size, but this scriptlet will definitely do the trick. Personally, I prefer tabs, so that I set my window size once and then don't pay any attention to it, but I know tabs vs. windows is a matter of personal choice!]
