It is not the correct way to do it. It has some very simple problems.

First, if I have a bunch of little windows on a big screen--something very common on Apple computers--I have to drag my mouse all the way to the top of the screen and then drag it back. For me, this was an serious problem. Partly this was because I was also using one of the horrible Apple mice (the "mighty mouse" or something of that nature). This was particularly annoying because I would often lose focus by clicking on something else by accident and have to go all the way back to my original window and then all the way back to the top... Incredibly annoying.

Second, not all programs have--or need--options on top. I essentially live out of Emacs and Chrome these days; neither uses a menu. That would make the Apple bar just a waste of screen space--completely absurd. Moreover, I've found that bar to be superfluous on other software I use as well. Having more minimalistic interfaces is a breath of fresh air--and completely impossible on OS X.

It also fails to generalize well to multiple screens.

Oh, and there are going to be problems if you want to make the available options context-dependent. This is a reasonable design decision if you have a complex program with a bunch of small, discrete windows for different tasks--something else that isn't uncommon on OS X. This sort of behavior is far clearer if there is a menu per window than if there is a single menu for whatever is currently active.
