The Segway got a lot of pre-announcement hype. It was referred to as "It" and a lot of well-connected people were allowed to see It and talked It up (at least in quotes splashed around the news) and the hype was way too much for the actual thing. Which got a "That's it?" response from most people and the press. It was supposed to be revolutionary, as big as the PC. It was a scooter.
