Exactly. The single menu causes quite a few problems, both obvious and subtle.

But yeah... now I'm relieved when I go home from work and get back on my Mac. I waste so much time hunting for stuff on Windows now... it's just incredible.

Pompous pedants used to trot out "Fitt's Law" in defense of the Mac's dumb menu all the time, when in fact it contra-indicates it:

"Fitts’ law states that the amount of time required for a person to move a pointer (e.g., mouse cursor) to a target area is a function of the distance to the target divided by the size of the target. Thus, the longer the distance and the smaller the target’s size, the longer it takes."

Right, so where should an application's menu go? ON ITS WINDOW. Not way up at the top of the screen. It's as if the people citing this "law" don't even read it.
