I'm looking at getting a Macbook Pro and would the processor to be as good or better than my last 3.06Ghz Dual Core iMac. Now, I thought that a mobile i7 processor would be as powerful as a desktop i7 if they ever had the same number of Ghz. But after trying to research further, I find that this might not be the case. Am I mistaken to assume this? If so, what performance differences would be seen during application and how/why?
