Rumors: Ultraportable Macbook and the Multitouch Trackpad

Macrumors is reporting that the rumored ultraportable Macbook we're hoping for at Macworld 08 is to have a multitouch trackpad and external optical. The optical makes sense, and is welcome. The multitouch trackpad rumor is a curiousity: Macbooks already use simple multitouch in trackpads for two-finger scrolling. Maybe a Leopard update will allow for things like zooming and swiping, like the iPhone. [Macrumors]
