I'm sure I've seen 5 or 6 of essentially this same thing on kickstarter over the last couple weeks. It seems to be a popular idea, but until the price drops enough for them to be disposable I don't really see the point.

That's what I thought of as well. Twine's, though not as robust, seems a more simple and elegant design. The question I'd like to know is who will take these systems and implement them in applications that have a greater "wow" factor for the consumer. Nest is a great example.

There are so many applications, especially when one considers location sensitivity relative to a phone.
