I&#x27;ve thought about that a lot, and I think new tech adoption relies more on the social framework that&#x27;s in place around it than we think. Simply put: if it makes you look&#x2F;seem like an asshole then it&#x27;s not gonna happen unless it&#x27;s too good to ignore.<p>Smart watches and bluetooth headsets are great examples: they work fine but they make you look like a tool because of the social frameworks we have in place (it&#x27;s rude to check your watch while in a conversation, it makes people feel weird when they think you are talking to them but you are just on your bluetooth.) Smartphones didn&#x27;t deal with this friction because there&#x27;s a long history of social rules around reading in public, and smartphones are essentially the same thing. We know when it&#x27;s rude and when it&#x27;s not, we know how to handle somebody reading next to us in the train, etc. In short, using a smartphone didn&#x27;t make you look like a tool, it was just the next logical step from reading a magazine.<p>I definitely think Segway fell victim to this.
