Yes I have the Serene back lately to wake me up and I have to say the Chime ringle wakes you up, far too well in fact because I cannot ever wait to turn it off!
The design seems interesting to me, but 300 and something £s seems very recession-delusional to me for an alarm clock. It's already returning value to my Serene which has an alarm clock in it as well!
However I have to agree with The Major ... please can we have an ML module for BeoSound 1 instead ... thanks a lot!
