Yeah, but then it's a one button mouse. Let's face it, just for the sake of being different, Apple has been pushing the stupid one button mouse for years. I couldn't live without my right click in excel and word.
No, it's like a 2 button mouse on top, with two extra buttons on the side. I though you were talking about the side button on your thumb side. Even if you set the two side buttons to do nothing, you still have the equivilent of a two button mouse. It's pretty clever. But the price is a little too high, IMO.
