Assuming we are all busy people with a million things to do.. Do people use notes/to-do applications on their phones to help them remember things (ie, tasks, people, memories, etc)? I had this thought.. what if we were able to "smell" something that would trigger this memory. Wouldn't it be much faster and efficient than say typing a note on the run? IMO, I think it would be epic if my phone could produce a scent that reminded me of someone I had to contact, or an errand I needed to run. What does everything think about this idea?
