I found this article interesting. It reminds me also of the Mobile Television services that have been successful in Korea and iMode, which was successful in Japan. Text messaging is another example of a technology that was successful in Europe but was slow to take off in the US (it has done so now -- ask any teen or young adult in the US).
These are the latest examples of technologies that have been successul in one country that may or may not translate to successful services in other countries. It is clear that cultural values are a piece of this, but so are living arrangements, communting arrangements, etc.
