3. DigiScents iSmell
Launch date: 2001
Fatal flaw(s): Ridiculous concept
For those of you that are unfamiliar, the iSmell was a product that sat on your desk and contained a cartridge with 128 "primary odors" that could be mixed together to form a smell that was supposedly emanating from a website you were visiting or e-mail you opened.
