Personally i prefer the way OSX does it. If you actually tried to understand why OSX does it this way rather than complaining you might actually see that it is a better way too.
I see people using programs like word full screen with two massive empty gray areas on the left and right side of the document. It's such a waste of usable space.
As opposed to OSX, where you have distracting holes with your desktop background and icons showing through. Rather like reading a newspaper with holes in it.
As you can guess, I'm not a fan of the OSX implementation. When I maximize an app, I want it to be the ONLY thing I'm concentrating on and I don't want to see other apps or my desktop.
