The iPad - contrary to the way most people thought about it - is not a tablet computer running the Apple operating system. It's more like a very big iPhone, running the iPhone operating system.

Apple enjoys 'Harry Potter'-like adoration and queues because it sells physical objects, limited by the pace of assembly lines in China. To own is to have, to have is to hold, and to hold is to show off.

The hours Facebook users put into their profiles and lists and updates is the labor that Facebook then sells to the market researchers and advertisers it serves.

It may be decades until we know what living in a state of constant distraction will do to us.

Facebook has never been merely a social platform. Rather, it exploits our social interactions the way a Tupperware party does. Facebook does not exist to help us make friends, but to turn our network of connections, brand preferences and activities over time - our 'social graphs' - into money for others.

Everyone knows, or should know, that everything we type on our computers or say into our cell phones is being disseminated throughout the datasphere. And most of it is recorded and parsed by big data servers. Why do you think Gmail and Facebook are free? You think they're corporate gifts? We pay with our data.
