I think what really rings hollow is that they keep trying to show people deriving meaning and significance in their life from "stuff".
Don't agree at all. I think that if you look closely at the ads, and really think about it, the people are deriving pleasure from life experience. Either listening to music that they love, or sharing something with someone else, or enhancing a once in a lifetime experience, or learning in a new, more exciting, more interactive and more effective way. The "stuff" in question is just allowing those things to happen more effectively, seamlessly and easily.
