I ordered a new 15" MBP with the 2.53 processor online and upgraded the hard drive to the 7200rpm speed. This is taking days to ship and Im impatient.. I'm about to pass by an apple store were they have they stock i7 processor configuration for basically the same price as my current order minus the faster hard drive. Would you wait or get the i7 now... Will I really be able to tell the differnce between the 5400 and 7200 hard drive or will the faster i7 make up for it? Any quick insight is appreciated!
