You know what’s uncomfortable? Standing in one place for an extended period of time. After just a little while, you want to either sit down or walk around. To facilitate this, we have chairs and shoes. Combining the best of both is the bicycle, which allows the user to (sort of) sit down while (kind of) walking around. So anyway, somebody finally realized that the Segway was a terrible idea and they’ve stopped making them. Which, hmm, why didn’t more people buy a complicated expensive machine to do something that can achieved better, cheaper, easier? Consumers can be so fickle.
