About 10 years ago, inventor Dean Kamen, in a much-anticipated introduction, brought his Segway to the public. Revered by the media and business-world celebrities as a total game-changer in urban planning, transportation, and daily life,  the public ended up a bit crestfallen at what they actually saw. It looks like a glorified scooter, and even today, it's a rare sight to see anyone other than a mall security officer or tourist group plodding along on one.

So what went wrong? How did one of the most buzzed-about innovations in modern times fall so short? It's easy to see Kamen's avoidable mistakes in hindsight. Take note to make sure the next product or service you launch doesn't flop.
