Personal -- because I always carry it with me and it is instantly accessible.
Information -- I have lists of: all the books I have read since 1985, my CD library, bank account numbers, schedules for the local public transportation system, area codes in the US, videos I have rented in the last year, books and videos that have been recommended to me.
Management -- I can add books, reschedule appointments, look up an area code, all with the stroke of a few keys, and always in the same place, the HP Palmtop. Brian Hollick CompuServe ID: [71023,464]
