I'm planning on buying another Mac this year, hopefully by summer, and I'm looking for some advice. I sold my MacBook Pro to a friend of mine, and here are the specs on it: MacBook Pro Mid-2010 15.4" Intel Core i5 2.4 GHz 8GB RAM 120GB OWC SSD 750GB WD Scorpio Black HDD Mac OS X Lion I was really happy with it, but it did lack processing power, which I crave when doing video. However, it is easy to upgrade, and it's portable. Why an iMac? For one, a bigger screen; even the 21" model would be great. It can use more RAM than the MacBook Pro can, which is a plus for me. However, I have read numerous articles about not being able to replace the HDD. I'm a technician, and I replace HDD's when they get close to being full. This is a downside for me. In the end, the question is this: how much of a difference is there between the processing power of the iMac vs the MacBook Pro? Is it enough to justify buying it? That's what I really want to know. Thanks!
