neat, yes, but necessary?

This isn't exactly what I would have predicted for the personal computers of the next decade to come equipped with. Apparently, fragrance cartridges will come with computers, to allow users to not only listen to their favorite music while working, but smell their favorite smells as well! Sensors in the computer will use the internet to deliver data about smells that will please the user. (At least I hope the smells will be meant to please!) This forecast was from a South Korean survey, which was compiled after interviewing over 3,000 Asian technology experts. survey also revealed that scientists are working on tiny robots meant to swim through our bloodstreams to target problems, phones that can go three months without charging, and military dress that changes to match its surroundings better. I have to say, the scientists working on the fragrance cartridges might find themselves more useful if they decided to help with the robots instead...
