It all depends on what you are doing.

The WindowsKey is often overlooked, for example, there are great key combinations for manipulating application windows. WindowsKey+Arrow moves the current window around in a logical way (up maximizes, left docks to left edge of screen, etc), WindowsKey+Shift+Arrow moves the current window to another monitor in a sensible fashion. Out of the box OS X doesn't seem to have equivalents.

You are right. This behaviour only appeared in Windows 7 +, and didn't exist on older OSes, unless you used a utility such as WinSplit Revolution.

On OSX, you can install something like ShiftIt, but if ANYONE discovers such a utility for Linux that is DE agnostic, I would cry with joy because I am using tile -m at the moment...
