Earlier this month Apple Insider reported that there might soon be an update to the Mighty Mouse and here it is. The primary issue with the now outdated mouse was the fragile, finicky roller ball locking up on Friday afternoons at 4:45 PM while trying to wrap up a project.
Apparently, the best way to solve the problem is to scrap the roller ball all together. 360° scrolling, screen zoom and iphone-like swiping sound great. I can’t wait to test one of these out.

Hooray! Met @shauninman and had a chance to demo @mimeoverse. Have yet to obtain the quantum glove though... it's so bad. 1 hr ago

But what about how the old mouse has the two buttons on the side, and you can personalize it to do.. lets say…. Expose- All Windows? Can Magic Mouse do that?!?!
Mal, we’re on the same page. If not side buttons, maybe there is a simple motion / gesture to expose.
