The (original) Honda Insight was a tiny 2-seater of a car, more tech demo than "ordinary" car, and perhaps it's the gift of hindsight but the Prius' popularity for with people that own one car, as a 4-door 5-seater car vs a non-sportscar 2-door 2-seater car seems all but guaranteed. (How many people do you know that own 2-seaters vs 5-seaters?)
Similarly, the vast majority of smartphones these days are (unfortunately) glass bricks, as first popularized by Apple. There were other interesting designs out there, but ultimately the iPhone design became the most popular smartphone design.
The first generation Prius wasn't exactly a hot-seller. It was still a compact car and the battery pack reduced the utility even more. The second-gen was the home-run for Toyota. It was about the same size as a Camry for not much more money and a lot of additional utility, especially around 2008-2009 when gas prices were absolutely crazy.
