Until now, I am really disappointed with the functionality of the PS3 towards other Sony devices (besides the PSP that is). I have ripped various CD albums to Atrac music files on the PS3 hdd, but it is not possible to transfer these to your (minidisc) walkman. If you connect your walkman, the PS3 states: "Unknown USB device connected". You can't even use it as an external memory device. In an ideal world you should be able to playback your songs from your walkman on your PS3. And it should be possible to use your PS3 to connect to the connect store to buy songs, not only for playing on PS3, but also for transferring to your walkman. And don't get my started about how you should be able to upload your songs from your walkman to the PS3 hdd. In conclusion: Sony has the potential to make the PS3 the Online music hub that they are talking about for a long time now. They just should implement the functionality into one of the next firmware updates.
