The iPod (line) – same thing. This is where Zune has done some innovating. In realizing that music is social, they’ve created features that let you temporarily share songs and see what others are listening to.
There’s no technical reasons why Apple would need to leave these features out. Traditionally Apple hasn't fully grasped the power of the open web, much less social.
But things are starting to change. Their acquisition of Lala is a huge deal. I can’t remember them ever acquiring a website — and a VERY social website on top of that. I’m ready for Apple to take these to the next level by injecting social into their products. They should start with the iPod audio player interfaces (iTunes, iPod, iPhone, iPad).
