In a follow up to the blog I wrote two days ago about Nordic Designers, especially Nille Juul-Sorenson and his remarks on the iphone's ability to become individualized.
Others have found an additional use for the iphone in the world of scientific research. It seems psychologists at Harvard have figured out how to do a scientific study by developing an iphone app. No need to enlist people to become part of a study. This study simply asks people all over the world to upload the app: Track Your Happiness.
It seems we are happiest when we are in the moment, when we focus.
