Kevin Keller has an overview of the "quantifiable self" movement:
About 400 people interested in serious self-tracking meet for the inaugural Quantified Selfconference in May this year. Self-tracking means monitoring quantities like your weight, sleep, location, messages, genes, body chemistry, performance, productivity, or any other of a thousand metrics. Self-trackers arrived from all over the world to share and explore the whys and hows of self-tracking. Self knowledge through numbers we call it. This emerging habit is being propelled by advances in cheap sensors, cheap communication, easier data tools, and our own interest in optimizing our bodies and minds. There are nowQuantified Self meetups in 10 countries, and over 200 startup companies in the field. Equally significant, a number of high profile venture capitalists attended the conference, indicating the movement might have reach some kind of threshold.
Through technology we are engineering our lives and bodies to be more quantifiable. We are embedding sensors in our bodies and in our environment in order to be able to quantify all kinds of functions. Just as science has been a matter of quantification -- something doesn't count unless we can measure it -- now our personal lives are becoming a matter of quantification. So the next century will be one ongoing march toward making nearly every aspect of our personal lives -- from exterior to interior -- more quantifiable. There is both a whole new industry in that shift as well as a whole new science, as well as a whole new lifestyle. There will be new money, new tools, and new philosophy stemming from measuring your whole life. Lifelogging some call it. It will be the new normal.
Good stuff. And, I believe, this is/should be the future of iPod.
iPod lives by becoming the brand name, the platform, the tools, sensors and accessories to allow *hundreds of millions* of people to quantify and review and share massive data about themselves.
The iPod brand is solid, but becoming marginalized. However, consider what Apple can bring to this tiny but growing market:
a history of the absolute best, most intuitive, easiest to set up and use personal mobile computing devices fully integrated with other (Apple) tools and devices
That's not nothing, my friends.
And we can instantly share/post every movement, every result, every bite we eat, via Twitter. And learn about these cool new devices at the Apple Store. And store them in the cloud.
This is a market waiting to happen. And, I think, the smarpthone will be a part of it: always on, always on, always with us; appropriate apps and sensors. But, I think iPod becomes the brand for all the tools and accessories this new market will demand.
