the dark side of mobility

From an InfoWorld article:

I went to the launch of Microsoft's Tablet PC in San Francisco this month. Bob McDowell, Microsoft's vice president of business productivity, who lives on an island off Washington, was the event's emcee.
McDowell told the audience that thanks to Microsoft and the high-tech industry, the dream of office automation was coming true. What was that dream, according to McDowell? Personal productivity.
Excuse me, but I thought the dream of office automation was a shorter work week? You know, more time for the family? But of course, no one has ever left the office even five minutes early since the introduction of the PC.
