Just unpacked my new iMac, the keyboard and mouse are powered up, paired, and discovered. BUT, I thought the "magic" of the mouse was that it's flat surface is supposed to work like a MacBook's trackpad. MINE DOES NOT. It just scrolls around, up and down within a window. Other than that, it works like a regular mouse, just move it, point and click. Is this right? Or did I mess up already? I called AppleCare and they say this is normal, but for what I paid, it should do more magic. Thanks for your answers.
