I agree...As much as I'd LOVE to get this, if it doesn't have a 3rd and 4th button it's useless to me.
I use my middle scroll ball as a 3rd button to open up new tabs, close tabs, etc.
I use my "squeeze" 4th button to show me all windows in Expose.
anyone else with me??
Yeah, I'm with you on this. I really wanted to purchase the Magic Mouse, but without 3rd and 4th button functionality, it's a step backwards. I use the 3rd button for Expose-Show All Windows, and I use the 4th squeeze button to show Spaces. Those 2 buttons work great together: show Spaces, then show me all windows. Great way to see all my windows in all spaces. Magic Mouse can't do this. I'll have to wait till the next mouse. Sad, cause it probably will take Apple another 3 years to come out w another design. Booooooooooooo.
