We've probably all known an executive who couldn't live without his or her BlackBerry.
And you may have heard that President-elect Barack Obama will likely have to give up his BlackBerry habit once he takes office.
Of course, after his device was accessed by some Verizon workers (who were put on immediate leave, though with pay), he might consider giving it up anyway.
It's a lesson for corporate execs - know who has access to your personal and company information, and keep it safe.
