I'm also not crazy about the menubar. Seems like it'd be hard to read. Also, it seems to be aping an aspect of the Vista UI which was criticized for that very reason.

What annoys me about the current menubar, is that when you have monitors arranged side by side, the menubar gets in the way when dragging a window from the secondary to the primary. And it's hard to arrange the monitors in the preferences so that the top of the secondary monitor is level with the bottom of the menubar on the primary.

What I'd really like is if each monitor could have its own menubar, and its own active application. So if you have Mail on the secondary monitor, you wouldn't have to mouse all the way back to the primary monitor every time you need to click on a menu. On two 30" monitors, that could be a very long way.
