The effect of communication via heterogeneous computer platforms, having different computing power, was studied. An analysis of solution times found that subjects with mixed platforms worked slower than their homogeneous counterparts. It was observed that a person in charge with a PC worked faster if his partner had a PC, and the PC-to-PDA combination took significantly more time than the PC-to-PC combination. Display disparities can take different forms, as they can result from physical characteristics of display devices, such as size, color resolution, aspect ratio, and spatial distribution.
