In my student years I've heard many of my friends explaining that they have chosen their particular field of study because they prefer to interact with people over sitting the whole day in front of a computer. Twenty years later they are all spending almost all of their days in front of computers, regardless whether they've become doctors, lawyers, journalists, financial experts or whatever. One of the more pronounced effects of general adoption of computers is that we have made all people desk workers regardless of their profession. I think that some of the most potent sources of continuing improvements in productivity is to unchain people from their desk. The personal computers gave people a great power but they also handcuffed them to their desk. One of the biggest opportunities of a mobile revolution, is that mobile devices unchain people from their desk without reducing computational power at their disposal. No wonder then that the venture capital is already moving away from consumer web and into enterprise mobile.
