That is a pretty good visualization. One of the things that really stands out is the growth in services. One way that has personally effected me has been with music on my iPad.
It has become harder and harder to have purchased music live on your iPad for playing. They have completely skewed what was their signature 'appliance app' (from the iPod of days gone by) from 'carry your music with you where ever you go' to 'portal to our pay per month music service'. Every time I upgrade IOS I worry about how much harder it will be to put my music on the device so that I can listen to it without being connected to a network or paying a monthly fee.
Don't worry - while the majority of users simply consume their music via streaming, local music ownership isn't going anywhere for music enthusiasts.
And as long as Apple allows alternative music players on iOS I'm not worried. I recommend Cesium to anyone using a local music collection: http://www.cesium-app.com/
It uses the same iTunes library as any other music app, including Apple's default music.app.
