Hi I have a freind who is comming from USA to Denmark with a black macbook for me, with 2.2 ghz, 4 gb ram, 160 gb hd for a VERY nice price. The new black model has 2.4 ghz and a larger harddrive. But here's my question: Can you tell the difference between 2.2 and 2.4 ghz? I don't care about the HD because 160 gb is more than enough for me. Should I be crying?
