hey i would really like a new MacBook Pro when the penryn ones come out, BUT i am willing to wait for a fair bit longer as i have no desperate need for it! So I am just wondering what the one after Penryn will be because iv heard Montevina mentioned and also Nehalem!!! Which 1 is it and also could someone explain the main differences between them and when would quad cores be in the MacBook Pros? I know its a lot of questions but I am very interested in this. Thanks a lot.
