There is an interesting download paper on the "The Untethered Executive: Business Information in the Age of Mobility" in the latest edition of Forbes Insight. As a member of the Forbes Insight Panel I thought you would be interested.
In summary the paper says" Much has been written about how smartphones and other mobile devices are changing the way people communicate. But little has been done to understand what the impact of this shift is on the executive suite. Are executives willing to use their smartphones for business purposes beyond email? Is the information they access via a mobile device being used to help drive business decisions? Do different “generations” of executives treat mobility differently, and are some more willing than others to blur the lines between business and personal communications devices? "
