Uh, the word your looking for is "anecdotal".
Anecdote is what you use when you don't have a good empirical rule. Empirical rules are, in turn, what you use when you don't have a good theory.
Since we have a good empirical rule in this case, excuse me if I'm not readily willing to abandon it in favor of anecdote...
It has been proven by real world testing time and again that what you're saying is infact true. The gain from using Fitt's law is lost by having more then one application on the screen and having to refocus the mouse to the application after you got it so far away from the application. The fact that you're saying its the same time alone is a bit inaccurate.

I've been a Mac user since 1987 and I used to quote Fitt's law and all the other standard reasons for having a top menubar. Then I actually tried timing my response and others to a request to find and click on a menu item under Mac OS X and Windows. My experiment found that having the menubar at the top of the screen made no measurable difference. My observation was that most of the time isn't spent positioning the mouse (the part Fitt's Law applies to), but recalling which menu to select and finding a menu item. Menus are not as efficient UI elements as buttons in terms of time to action, Fitt's Law proves this, and so you gain nothing by putting menus that change per-application at the top of the screen. My theory is that the top menubar is a hold-over from the original design before the Mac could run more than one application at a time, then it made a lot more sense and Desk Accessories had no menubar probably for this very reason. I don't think Apple revisited the menubar when they were forced to implement the MultiFinder to stay competitive.
GNOME uses mostly static buttons (with the exception of three static menus) in locations positively effected by Fitt's Law. GNOME has correctly applied Fitt's Law and Apple hasn't in this case.
