You know, that type of wear CAN be caused just by finger-tips. Some of you may have noticed that for the last few years manufacturers have been using this "soft-touch" ultra thin rubbery coating on tons of things to make them more pleasant to touch (computer mice, DAB radios etc etc) and these keys appear to have the same thing on them. My last Logitech mouse developed these round worn patches just where the fingers rested. I wasn't even actively tapping or gripping those surfaces tightly. This wear did occur over a period of years though, not months, so i'd guess the guy who owns that keyboard must be one of those addicted WoW gamers who doesn't sleep. That, or the thickness of the soft coating is incredibly thin.
The country of origin is no indicator of quality. Any nation that can send men into space and return them safely to Earth is capable of producing a decent keyboard, as incredible an achievement that may be. It is only tight-fisted companies who want to maximise their profit by paying for cheap materials and half-assed labour, and consumers who want something for nothing, who cause bad quality products to flood Western markets.
