For more than ten years I've been involved in the design, installation and aftercare of home-theater, multiroom, lighting control and home automation systems. We at Dark Side of the Room install systems that people actually use every day. The key to success is designing systems that are as easy to operate as a standalone TV or FM radio. Add a few no-brainer automation to that (for instance : when the lights in the bathroom are turned off, power-off the radio) and the result is something that actually makes one's life easier. Pretty much like central-locking in your car. Or automatic lights and windshield wipers.
