All I know is that most tech companies follow one of two paths: They either try to make a product that looks like everyone else's (e.g., pretty much every PC I ever owned) or they rely on obscure techncal features to differentiate their product (which only engineers and techies care about). Apple and Nest both have reasonable tech specs and features, but they rely on the way their products interface with humans to differentiate them. What an interesting (and apparently profitable) concept. My big hope is that some of the HA companies learn something from this.
