Insights from Generation Y: Useless Invention Ideas

My brother J commented yesterday: "Nothing good can come of inventing a smell-sensor/simulator for cell phones."

To support his argument, he pointed out the following:

1. You rarely smell anything nice in life. (Can you actually remember the last time you smelled flowers?)
   
2. Nice smells (e.g. food) can actually smell bad without the proper context or when you are in the wrong context (e.g. crowded bus).
   
3. You frequently smell bad things.
4. Taking observations 1 and 3 together, he pointed out that you often do not notice that you have a sense of smell unless you smell something bad.
5. Finally, he noted that we are far too immature to be trusted with being able to SMS smells to one another. (Note: what is transient but would be funny to send to someone else?)

I think there is really only one smell I really really like: the smell of rain as it first hits the ground.
