Very interesting article I stumbled upon in Low End Mac a few moments ago: According to the testings of Low End Mac Read more about it here: http://lowendmac.com/musings/09mm/cpu-efficiency.html Looks like those who are getting the low end 13 Macbook Pro is essentially getting a the performance of late year's high end Macbook for a much lower price. Making this generation of 13 inchers indeed a great deal. I do believe however that the older 2.4 Ghz unibodies have higher capacity HDs - those can easily be upgraded. The 13 MBP is indeed the spiritual successor of the 12 Powerbook. And I'm really tempted to get one myself.
