A portable electronic device is provided comprising a processor, a memory, a loading application stored in the memory that accesses loading criteria for a first, second, and third ID wherein the criteria comprise measures of relative importance applied to variables associated with each of the IDs and wherein the IDs comprise at least one of an application, a media file, and a widget. The system determines a current value of at least one variable wherein variables comprise at least one of day of the week, time of day, and geographic location of the device and additionally comprise a first, a second, and a third event status associated with the first, second, and third ID, respectively. The system applies the criteria to the current values of the variables to determine a composite loading factor for each of the IDs and loads one of the IDs based on the factor.
