I voted for 2-way communication, as for me this is becoming the top priority in B&O systems.
Having BeoPort/BeoPlayer, it is a real challenge to find the right track or station if you're not in front of your PC, and I can imagine that it is soon going to be the same nightmare for DTV stations once you get thousands of them to choose from.
This was B&O's exclusivity 20 years ago, as was the display on the loudspeakers, and they gave up this exlusivity..now, as for the wheel, once (if) they go back to it, people will say they copied Loewe or Apple!
However, I wish there had been another possible choice in the poll: integration.
It drives me crazy to see that DVD2/HDR2/BeoMedia could have been one single product, for the sake of simplicity & convergence of technology. A single audio & video platform with add-on modules would be the way to go, I think.
