The main thing for which I still have to turn on the TV and/or use AWXi (a web interface) and I do this very often: start playing (music) playlists, in order or even more in party mode. Also because one has to use music playlists to be able to tune in to webradio (i.e. a playlist that contains an URL), playlists are important to me. I've been helping out with AWXi development to enable playing/party mode of playlists, but I recall that the API is a bit unsufficient or requires some hacks. I am not completely sure as AWXi uses a mix of the HTTP and JSON API still. Maybe in pre-frodo things are looking better.
