Excerpt from an iPad-in-the-workplace reality check
To a large extent the iPad’s entry into the business world was paved by the iPhone. When Apple first released the iPhone, it lacked capabilities to link up securely with corporate e-mail systems. But as executives tried the device, they often preferred it to their BlackBerrys and other smartphones, and soon began demanding support for them.
Apple gradually added capabilities, and the iPhone became standard issue in scores of large businesses.
Companies that waited two or three years to support the iPhone began adopting the iPad just weeks after its release.
