AI found Apple unceremoniously selling 8GB kits for its newer model 15-inch Unibody MacBook Pros (not the older 2.5GHz model). It is the same kit as they sell for the 17-inch unibody Macbooks and it is the same price. $1200. If you have to ask
Not to worry though, hardcore RAM fiends, OWC has the same kit for a paltry $719. Amazon has it for just over $1000.
