This is form.

After reading all of the hype and hate and recouping from the move to Austin, I decided to try it for myself. You should first note that I hate wires and I have owned three of the wireless mighty mouse. My initial response: It is much lighter and feels nice in the hand. The momentum scrolling is I think my favorite part—when not using the magic mouse, scrolling seems weird. I also use the hot corners for exposé so the removed buttons make no difference. The verdict: I like it and recommend it.
