Well, I talked with Apple. They did not seem to worried about it at all, they didn't even want a store to look at it. I haven't had any performance issues, so not enough moisture to set off any water sensors. However, the representative did note that I have 30 days to exchange if I so desire (I thought it was 14 days?). The rep created a "case" that has this documented just in case anything arises from the droplets. I would feel a little picky by replacing it, but on the other hand I thought Apple had such stringent standards on the refurbs. To receive one that has diminished cleanliness is a little disappointing. Any suggestions on swapping it out just to be on the safe side...if nothing else to save me possible headaches down the road? Or just roll with it?
