Doesn't surprise me, Witten, Bochum, Dortmund, it's all completely intertwined, but Dortmund is the center ;-)
Coming back to the mini speaker topic, I successfully tested the Bang & Olufsen 'basket' in the store today, it has no signal latency and a sound which appeared more powerful than the Bose Sounddock portable to me, so I believe the spec of 120 W RMS. I guess it'll be mine by Thursday (the 'special offer' will end then), and I'm going to sell one of my Bose docks (which I never thought I would).
