Everything we do in the digital realm - from surfing the Web to sending an e-mail to conducting a credit card transaction to, yes, making a phone call - creates a data trail. And if that trail exists, chances are someone is using it - or will be soon enough.

We're living in an economy where productivity is no longer the goal, employment is. That's because, on a very fundamental level, we have pretty much everything we need. America is productive enough that it could probably shelter, feed, educate, and even provide health care for its entire population with just a fraction of us actually working ... Our problem is not that we don't have enough stuff-it's that we don't have enough ways for people to work and prove that they deserve this stuff.

It's also hard for people to contend with the difficult possibility that we are simply overadvanced fungi and bacteria hurtling through a galaxy in cold, meaningless space. But just because our existence may have arisen unintentionally and without purpose doesn't preclude meaning or purpose from emerging as a result of our interaction and collaboration. Meaning may not be a precondition for humanity as much as a by-product of it.

The early cyberpunk idea was that networked computers would let us do our work at home, as freelancers, and then transact directly with peers over networks. Digital technology would create tremendous slack, allow us to apply its asynchronous, decentralized qualities to our own work and lives.

To buy an Apple product is to bet on the longevity of the closed system to which we've committed ourselves. And that system is embodied - through marketing as much as talent - by Steve Jobs.

The new Zune may not be an iPod killer, but it does offer a clean interface, great industrial design, HD radio, and a subscription model for music, making it significantly less expensive for big users.
