Anyone have a comparison on how 'hot' the old x1600 Core (1) Duo macbook pro models were? Were they the models that gave the MBP the repuation for being scorchers? I believe that was called 'Yonah' at the time. I can get a really good deal on one, which I can hold onto until the new-new one finally releases, so I'm throwing that around. Any other widespread issues from this generation?
