Next year you should ask santa for a Beosound 9000 perhaps?
But it really depends on how you like to enjoy your music... If you are happy with the powerbook as source, you don't really need a beosound... But what about a beocenter 2, then you can also enjoy DVD playback on your MX...
ENJOY!
best regards
