I mean when there is no "enterprise" market. Tech is changing, devices are getting smaller and more powerful. The need for "enterprise" software/hardware is slowly dying.

Eventually "enterprise" will mean big servers of data. And that's about it. Look at Google Apps (and others like it). It's fee for services to anybody. You pay for what you want and it's accessible to everyone - corporate and the joe on the street.

Now granted, Google Apps (and all the rest) have a long way to go. But they will get there. And sooner or later, companies won't have to buy 10,000 copies of Office, or spend $300,000 on a database.

I see the day when a company joins Google Apps, and says "I need 25TB on Big Table".

I think what was meant was something like "when the enterprise market reaches a tipping point and gravitates en masse to substantially less expensive but more or less equally effective technologies, the way that consumers and smaller businesses have already done."
