If they want to clean up the UI, they should start with the menu.
The apple menu is in its basis very nice and of course, removing it would be an axe-cut (and me myself, would remember it as an icon). But look at it. At least two items (App store, Dock) do not even belong here and the others are only used sparsely as they can be activated quicker and more securely (have you ever accidentally put a remote computer to sleep with the menu?) by pressing the power-button. The only thing really useful for a user is System Preferences.
The Application menu: The only things really belonging here are the preferences and Quit. About belongs to the Help menu and Hiding belongs to the Window menu. Barely any application ever uses this menu for anything else (including apples own applications).
Ditch the window and Help menu alltogether and find a better solution (for example a button on the right of the menu for help which can be turned off for the entire system if wanted.) The window menu could have been ditched since the introduction of exposé, but unfortunately in Leopard and with the new Magic mouse, exposé became increasingly uncomfortable (And grand-master-control-central-station-whatevertheycallit will not make it better), so I ended up using the window menu while I have never used the menu before the changes. So for now, I need the window menu but I know, there are better ways to solve this (and I don't mean single-window applications).
Now this would need some get used to but if Apple looks at computers user-centric nowadays, the menu as it is is just not conformant to that idea.
