They're saying that it's the future of digital music - no need to "own" any music yourself - you just play whatever you want through spotify but unfortunately you have to put up with ads popping up every so often.
Not sure what you do when you're away from your pc but I suppose they're assuming that before too long most people will be able to get streamed digital music just about anywhere through wireless, 3G or whatever.........
PS I know I shouln't be telling you this in these hard times but I've just been to look at a new car with a USB connector for the iPod
