I'm planning on getting an MBP this week, and assuming there is no Merom update, I'm looking at the 1.83ghz refurb models Apple is selling. They no longer sell a 1.83 new - 2.0ghz is the bottom of the line. I'm comfortable with refurb products in general, and I'm getting Applecare just in case. However, should I be worried that a 1.83ghz will have an earlier revision of the logic board, or other components that would make it more likely that I'd have the problems (whine, moo, etc.) that some MBP owners have had? I think I'm safe in assuming that the battery will not explode, but these other issues worry me a little more than they would with a new MBP. Still, it's hard to justify more than $200 extra for a new model, even at student prices. Anyone have any thoughts?
