I just hope Apple is working on not one, but three social platforms:
music + music store to compete with soundcloud, mixcloud, myspace
video + video store to compete with youtube and vimeo
photo to compete with pinterest and flickr
Don't mix them up. Just let it do one thing very well.
Ah, and don't listen to Bono. His idea of having the band members in 3D is just plain silly. It is about the music. I have no desire to play with a 3D Bono. Keep It dead...
