One of the big factors with Sonos that you won't get out of receiver setups is the ability to mix-and-match inputs and outputs over a whole house: having one speaker by itself playing the news in the morning, having everything in the house playing synced music on low in the afternoon, and having the home theater set playing a movie in the evening. Not needing speaker wire adds to that convenience: you can then stick a speaker in the garage or the bathroom in the future without laying more wire, as long as you have an outlet. Of course, all of this isn't exclusive to Sonos, but from what I understand none of the copycat competitors have matched their ease of use so far.
