Sounds to me like someone either in the engineering department or the manufacturing department needs to be fired, cause, in my opinion, that's just plain negligence of due diligence. The difference between American (60 Hz) and European (50 Hz) electronics specifications is very well-known. Further, those cycle differences aren't just NTSC vs. PAL video standards, the electricity in the different regions cycles at those frequencies. Even more so, the standard voltage of electronics in European nations is different from the American standard. Again, this is all very well-known. Not much excuse for any world-wide distribution of electronics to not have accounted for this very basic fact.
I mean, holy hell, 2 seconds on Google (literally) pulls up this http://en.wikipedia.org/wiki/Mains_electricity_by_country. (Come to think of it, I need to keep this in mind myself, if and when I have to ever travel overseas and deal with plugging my laptop up somewhere. Have to find an appropriate voltage-cycle converter.)
