In addition they purchased Fingerworks, who began working on capacitive multitouch sensing and gestures in the 1990s. I believe the founders of Fingerworks held several patents in that area--and still work at Apple today.
I have a Fingerworks touchpad and it is amazing. Apple is slowly rolling the gestures in their products. For instance with Lion the "click and drag" gesture went from a double-tap-and-hold (Apple standard for years) to a three-finger drag (what it is on my Fingerworks pad).
