In the fall of this year, I have to go away to college and I want to get a laptop. Certainly I want this to be the macbook pro. However, I also need a laptop right now. Should I buy one of the macbooks now with the yonah cores or wait until the merom core is released. If merom is to be released in the fourth quarter of this year, that would probably be too late for the start of classes. Will having a merom core really make a difference? I am lead to believe that 64 bit software is still a ways off from becoming practical, so should I just get one of the macbooks now?
