Bought an open box 13" MBA from Best Buy and it has been great except for one tiny issue.....it has a (somewhat) odd smell. Day 1 it kind of smelled like bug spray, but it has since dissipated to the point where it is a very faint smell. I *think* they (Best Buy) may have used some sort of solution to clean the screen or perhaps even the outside case, but I cannot be sure. I am not even a week into this computer, so I'm well within my 45 day return window. It has been running without a hiccup, but my main concern is that perhaps there was some water damage done here and I wanted to see if there were any exterior indicators that could let me know. If not, what would be the best way to check for that?
