According to a report by Asahi.com, Toshiba is developing a new technology that can turn cell phones into virtual secretaries. First, it monitors a user's current behavior patterns and location. From there, it will "predict" that person's future actions based on the available data and give relevant information, much like how a real secretary works.
Like many of Japan's mobile-related technologies, this will probably be available only in its home country initially. Those who we imagine will benefit greatly from this are wives who are constantly suspicious of their husband's pretty assistants.
