The next models of the MacBook Pro edition will have a multi-touch pad. Apple's exclusive multi-touch technology as placed in their IPhone and ITouch will now be implemented in their MacBook line. The implementation of Apple's multi-touch in their laptops did not take very long as stated by AppleInsider "In very much the same way that iSight video cams have become commonplace on nearly all of Apple's personal computer systems, the Mac maker will reportedly scale the gesture-based input technology across its notebook lines during the course of the year."
And also the New Notebooks will also have Cupertino-based company to employ Penryn-based Core 2 Duo mobile process from Intel Corp. Which means the New notes books will run better and faster then the older version. "which in their most likely form for the MacBook Pro would range in clock frequency from 2.5GHz to 2.6GHz with 6MB of Level 2 cache."
