As PDAs become more powerful, and memory becomes cheaper, more people are carrying around a lot of personal information in an easy-to-lose format. The Washington Post has a story about this:
Personal devices "are carrying incredibly sensitive information," said Joel Yarmon, who, as technology director for the staff of Sen. Ted Stevens (R-Alaska), had to scramble over a weekend last month after a colleague lost one of the office's wireless messaging devices. In this case, the data included "personal phone numbers of leaders of Congress. . . . If that were to leak, that would be very embarrassing," Yarmon said.
