What wasn’t clear before is the fact that music can be either streamed or downloaded locally to any of your computers or devices. While the video only shows the service on a Mac, we’ve confirmed it works the same way on iOS devices. So, essentially, you will have instant access to your entire music library from all of your Macs, iPhones, iPads, or iPod touches for only $25/year. This ability on your iOS devices means your music library won’t need to take up valuable space on the device itself, as long as you have some sort of internet connection.
It really sounds like Apple is setting this service up to be a real competitor to something like Spotify or Rdio, just for people who already own a ton of music. It would be a lie to say I wasn’t excited about this.
Update: It seems this is wrong.
