Says Steve Jobs in an interview with Steven Levy for Newsweek.

The iPod is five years old next Monday. Steve Jobs makes an interesting remark about how and why Apple got it right: ‘One of the biggest insights we have was that we decided not to try to manage your music library on the iPod, but to manage it in iTunes. Other companies tried to do everything on the device itself and made it so complicated that it was useless.’

That is surely right — library functions must work from the network and belong to the centre. Its a mistake to build the library at the periphery. A good architectural principle, which must apply to magazines, periodicals and books just as much as music.
