24. DigiScents iSmell (2001)

Few products literally stink, but this one did--or at least it would have, had it progressed beyond the prototype stage.

In 2001, DigiScents unveiled the iSmell, a shark-fin-shaped gizmo that plugged into your PC's USB port and wafted appropriate scents as you surfed smell-enabled Web sites--say, perfume as you were browsing Chanel.com, or cheese doodles at Frito-Lay.com. But skeptical users turned up their noses at the idea, making the iSmell the ultimate in vaporware.
