Whatever Happened to Smell-o-vision?

A few days ago, after archiving my old magazines and books, I happened to come across a little piece of nostalgia. Shuffling through all my books, I finally saw the cover to "the Official Dreamcast Magazine" #3 where Lei Fang of Dead or Alive fame was plastered all over the front cover. I turned the pages to get a feel of how much the gaming industry has changed these past 9 years and nonetheless I was quite flabbergasted.
"Damn," I said to myself, "Konami was actually thinking about releasing Reiselied (AKA Ephemeral Fantasia) on the Dreamcast back in the day." But enough about that. There's actually one article that I found of interest in that whole magazine, and that was the proposed idea of Smell-O-Vision making its way into video games. The proposed idea was that some dude apparently patented some idea of speakers that would give off scent whenever you went into say, a field of flowers, and such. I remembered reading something about this in numerous articles and they always spoke of the promise it could present by immersing people further into the movie/gaming experience.
Well, nine years later, still no Smell-O-vision. I wonder what kind of experiences we would have had as gamers had smell-o-vision been full force implemented. Would you have been able to smell the charred remains of Elites in Halo? Would those beautiful environments in Ico and Shadow of the Colossus actually been more impressive and that much more beautiful? The world may never know.

What do you all think gaming would become if aromatic environments were implemented?
