I am thinking of getting a referb (my fist refurb and MBP) MacBook Pro. So I would like to know how much faster is the 2.5 vs. the 2.6GHz with 2Gb ram. I will be using it as an All purpose computer in my Home Theater and as a vacation computer as my air is just not powerful enough. So it will be storing (but mostly just accessing from my iMac) video data. Minimal Video Editing.
