An observation for me has been most of your technology post relates to internet, other areas ( like telecom importantly, seminconductors, networking enterprise software etc are almost non existent). I am sure you might understand the dynamics of those areas too very well but why no posts on them.
Just a few other thoughts on this data. Note:
- this service is a "walled garden" such that those songs are unusable on any other device other than the original mobile it was downloaded to.
- Japan has had a CD rental marketplace for decades, where customers can "rent" a CD for a few hundred yen (a few dollars) albeit the newest music is not available
- All of these customers are on KDDI/AU's 3G "WIN" network and are almost all on an "unlimited bandwidth" package (in contrast with 2G services which charged users by the packet! can you imagine?!?!)
So, my point is that even though the cost for this service is (to me at least) higher than iTunes and less "portable", there is enormous demand for downloading "full songs" to one's mobile.
