Hey, So I just sold my laptop & desktop and I'm looking to just have one laptop so I've decided that the 15" Unibody MBP is gonna work. I mainly do internet/email etc, I'm a business student so I occasionally need windows so I'll do a dual boot with Vista Ultimate (7 once it's officially out). The one thing I do that's intensive is occasional 720p video editing with iMovie, and watching some 720p videos/converting them so I can watch them on my PS3. So I'm looking at either the current 2.53GHz 15" MBP with the 9400 for $1599 (education price) and selling the free iPod, or getting a refurb 2.4GHz 15" with the 9600 for $1349, and I'd need to buy 4GB of RAM (~$60 on newegg). Will the 9400 be good enough for light video editing or should I get the refub and up the RAM?
