On the other hand, I know several people who have Crestron/Lutron systems and the husband is sometimes okay with it (hardly ever uses it), but the wife usually does not care for it.
It is a sad affair out there. Joe technician takes a couple of classes and all of sudden, thinks he works at Apple and knows how to design interfaces using Crestron/Lutron. I think not. There are a ton of systems out there that are non-functional as a result of poor cookie-cutter designs.
We just ripped out a complete Crestron system and put in a simple HomeLogic for a customer and they are super happy with it. HomeLogic is like Control4 and so is a step down from Crestron but for this customer, this is all they need. Of course I am happy about this as I get to have more Crestron gear for my house

The best automation system is one that you don't even know is there anyway. Systems should predict what you want it to do and do it without user interaction. My outside lights at the house go off at sunrise. I don't have to do a thing for that to happen (they also go on at 20% after sunset to give us safety). The system clock adjusts for days of the year and it always knows the right time to do that. This saves energy but more importantly, me having to replace bulbs in really hard to get places.
The typical lighting automation guy instead brags about useless things like "dinner scene" button. What the heck??? How would somebody come to the house know what a dinner scene is? Mine says "Chandelier." You hit the button and guess what? Chandelier comes on

. The On button is always on top and always turns on expected set of lights at appropriate amounts. In the kitchen, in addition to the main lights, it also turns on the pendant lights over the counter at 10% just to make them pretty but not waste power (separate button turns them on fully if needed). Off is always at the bottom so as with mechanical lights, you can operate them by feel rather than trying to read their labels.
Anyway, these systems are custom and can do as much as little as you need them to do. For me the opportunities to bring more convenience, energy efficiency and safety make them worthwhile in higher-end homes. Automation for automation sake is terrible. But there really is great uses for the technology in good hands...
