My biggest peeve with control systems is the inability to manage music the way Sonos does. I swear once Crestron, RTI, Control 4, Savant, Yamaha, Denon, Bose..etc..figure out how to handle all music services without having to use another app, things will be great. Right now I'm just considering Sonos for everything that requires music. Nothing beats using one app to turn on rooms, adjust music and search for music. You could build a business based on Sonos, TV and Network systems installation alone and your customers won't complain about things not working all the time.
