In the library world, we rely on technology. We e-mail our colleagues and co-workers. We use the web to find information for us and for others. As a profession, and like many other professions, we've grown increasingly attached to digital communications and we'd find ourselves hard pressed to make do without them.
Not so with the highest office in the United States. The President of the United States really doesn't engage in e-mail because of laws regarding the archiving of Presidential communications, but also because of security. While the ability to send a message instantly to POTUS is a powerful thing, if that message contains classified information and it's intercepted by a hacker, then we're talking a matter of national security.
Nevertheless, our new President is a bit of a geek and is addicted to e-mail and his BlackBerry. He's explicitly stated that "They're going to pry it out of my hands."
So how do you provide the security needed by the President when all he really wants is to use the same tools millions of people use every day? Simple. You get him the most secure BlackBerry ever made.
