Reading this review what came to my mind was function creep.
What you need to do is have a listen to something like the Linn Sneaky Music DS (or Klimax DS if you're feeling flush).
It doesn't make a cup of cofffee for you whilst you listen to your music but what it does do is reproduce music better than any other network music player. Not only that but its software is open source, it's a UPNP player and it is scottish designed and built.
You could also try things like the NaimNet although I haven't heard it yet and it is quite a bit more expensive than the Sony.
These options are a little more expensive but sound alot better than your mass produced sh*te from Logitech, B&O or Sony.
