and from what I can tell, it's one of the dell ones that is being sold as a sonic blue one. It even has a "sonic blue" sticker that can be peeled back and "DELL" is underneath :-). Anyhow so far I've gotten it to work under Linux and have even setup the linux server from Jeff Mock. The only reason I'm not still using it though is it's lack of playlist support. I bought this so my fiancee could listen to our mp3's in the living room and without playlist support it won't be of much use to her. I've seen the other software servers but was hoping someone could tell me which one of them they think is best? Obviously playlist support is a must, and reloading or adding new music is easy. Basically I want my fiancee to be able to sit down, setup a playlist and load it. She CAN follow directions and use computers, she's just not a techy person.
