Cultural Aspects of Computing?

Sean80 asks: "Recently, my company discovered that cultural aspects impact significantly on the expectations for a piece of software. For example, we found that the features which the Japanese would like differ markedly from those demanded in the US. In one particular instance, the Japanese market seemed far more demanding of functionality which dealt with quality issues. I am trying to find good books or other resources which address this issue. Are there any out there? What other areas of computing are impacted by cultural considerations? Should I consider these differences when building UIs, for example?"
