1. A spatially associated personal reminder method, comprising: receiving current locative sensor data, the locative sensor data identifying a physical location of a user's portable computing device; accessing a reminder database containing a personal reminder, wherein each personal reminder comprises reminder content and a trigger area relationally associated with the personal reminder, the reminder content identifying one or more tasks the user intends to complete in the future; determining a current entry state of the user with respect to a trigger area that is relationally associated with a personal reminder by comparing the physical location identified within the current locative sensor data with a boundary of the trigger area; accessing a piece of historical data from a memory of the portable computing device, the historical data being used to determine a previous entry state of the user with respect to the trigger area at a just recently past moment in time; assessing whether a trigger event associated with the personal reminder has occurred based at least in part upon the current entry state and the previous entry state; and alerting a user to reminder content relationally associated with the trigger area when a trigger event is determined to have occurred, the alerting being performed via a display of the portable computing device.
