One conference we were demoing the alpha boards at last year had a newly installed carpet. People kept coming up, index finger extended, and saying: "Oo! Is THAT the chip?" *Bzzzt.*
That particular board still works. So does the one that's spent the last six months in JamesH's backpack, the one I've taken on four (eight if you count returns) transatlantic flights in hand luggage, the one in the study that my cats occasionally nuzzle up to, and the one Dom fed power to through what turned out to be a piece of wet string he had accidentally mistaken for a USB cable. (Long story.) This is not a great dataset, but my feeling is that you've not got much to worry about.
