I WISH AN ECONOMIST INTELLIGENCE Unit Survey would document the productivity that traveling business workers enjoy if they can access free and open wifi service. It doesn't even have to be as fast as the screenshot at left. Four years ago, the Economist revealed that "63% of companies (are) currently evaluating or implementing wireless technologies. The top benefits perceived by companies are that it supports flexible and remote working (46%) and helps employees use travel time more efficiently (40%). Thirty-five percent also felt it improved collaboration between dispersed teams. Twenty-four percent cited keeping on top of e-mail as a personal benefit." All these benefits are part of my work life. But perhaps the biggest benefit I enjoy is running Seesmic video conversations and Online Meeting Rooms for class work while untethered from the scheduled classroom environments.
