There is very little business that cannot be done these days with conference calling, faxes, email and video phone, yet these business men are still more comfortable with the idea of actually travelling themselves rather than trust it to technology. As an example my friend has just returned from a week schmoozing in Tokyo in order to increase customer relations.
