If it ain't broke don't fix it, said no Apple developer ever.<p>Part of me wants to believe that they added a single slab of a touchpad mouse, created something completely different, so they could not only patent the technology but also patent the "Apple difference" in their machines. I sure as hell prefer to use the traditional 2 button style on my Thinkpad. I can even use touch scrolling and do nifty 2-finger click stuff.
