what about Mac Mini (Score 1)

I am experiencing a similar color changing experience with several Mac Mini's as well. After just 6-7 months, I can notice the upper cover of the cases getting yellowish, old looking, exactly like if somebody was constantly smoking on them (which is not the case). When I went to the local apple store, I saw their older Mac Mini in the showroom being far more yellow than mine. Also the contrast with the bright white cover of the newest dual core models was evident. I wonder what colors I will have the pleasure to enjoy in a couple of years and if other users are experiencing the same.
