My pre/pro has bluetooth, blu-ray, plasma, would be nice to also have it work lights, don't know if i can use it for pc, probably through Sonos, not sure. Also be able to use it on the bedroom system. Being able to use a smartphone app would be awesome. I may yet put the audio tower in another room, so flexibility is important. I figured the Harmony line would see me through most changes for quite a while. It looks like the ultimate is what I will go for. On e-bay things get mis-represented, and I just wanted to be sure which one I was looking at.
