If you've grown up using the poorly crafted Mac OS interface, you probably don't realize that almost everything else is slower, despite that one really fast menu access (by mouse only).

However, I can Alt-Tab to an app and bring up it's main menu (and hunt through the menu) with only the keyboard. You just can't do that on the Mac. There's a reason most other desktop systems copy the much more logical Windows style instead of the illogical Mac OS style.
