Is it me or is home sharing nothing new? I can't seem to understand what's new about the feature... Apple says you can now authorise up to five computers in your home to share together with purchases. Couldn't we do that before with iTunes 8? Or not? Can we do this ACCROSS iTunes accounts within the home? (That would be understandably cool). Even if this sharing purchases within the home is a new feature....surely it's being over-hyped?
