I'm one of those who use the PS3 as my primary (only!) media center. It works well with my NAS and supports DLNA.However, it lacks my favourite music service: Spotify. A Spotify App in the PS3 would be the most awesome thing since sliced bread! I realise that the challenge in making this feature happen is more about politics, distribution rights and negotiations with Sony than about tech development. Still, I'm one of your users who'd really appreciate the effort!
