I don't think I would buy it today if that is what you mean. But back in the days when I bought it, smartphones were almost non-existent, let alone anybody could predict what their possibilities would be in the future. (like eg. controlling the home automation)
But now the house is finally coming together, and this is one of those things on the "to do" list. Hardly imperative, since I can command my home automation with my phone and iPad as said... but I have it, it cost me 600 euro back in the days and I would like to be able to use it now. It will add an additional level of comfort. Besides, it's been sitting in my wall for years now and everybody that comes in bugs me with a "hell, did you get that thing to work already?"
