i have a friend who for some reason wants to switch his 2.53 unibody with un-removable battery (8 hours of batt i think) with my unibody macbook pro 2.4 with removable battery. He offered for this switch as long as i payed him 200. Is it worth it on my end? My macbook pro has the 9600 gt, but i never use it. Tell me if its worth it for 200 more, for the added battery, and such..
