This is one of the reasons why the folks at Sirius would be in charge after a merger and why XM has faltered. Not that they are that much more smart, but definitely smarter. XM makes the worst business decisions. 5.1 surround sound for my stereo? Yea something everyone wants. It's yet another useless marketing gimmick. XM signed up for this trash in 2005 and like paying Oprah $50 million to be on the Oprah channel for a 1/2 hour a week, yet another horrible marketing decision. I doubt anyone but the idiots who convinced XM to go in on this have this ability. And if they do, I doubt they actually use it.
