Somehow I never realized you could hold Control and zoom the whole screen with the Mighty Mouse ball. Cool! 
There's no good reason Apple couldn't let ALL mouse wheels do that, and I'm not a fan of how Mighty Mouse handles right-clicks. I'm also disappointed that it will not register a squeeze DURING a drag (which would be nice for Exposé or UT rocket firing). But this animated OpenGL full-screen zoom is too cool
I'm always using the zoom keys for that anyway, but the ball is easier. And unlike the keys, it doesn't require Universal Access Zoom to be turned on.
With smoothing turned off, this makes pixel-precise work really easy in any app. It's just so easy to zip in for a close look and then zip back out.
I really like that ball. And the mouse's shape, too. Hopefully I can get used to the right-clicking, or I'll be stuck with my big ol' shoe-shaped Intellimouse
