This study investigates the relationship between microcomputer playfulness, an individual’s intention to adopt an information technology (IT), and their attitude toward adopting an IT. Analysis indicates that microcomputer playfulness is a significant variable in the determination of attitude toward adopting an information technology as well as end-user intention to adopt. The identification of high and low playfulness individuals, and the characteristics they deem important regarding innovations, allow the organization to customize technology introduction, training and implementation processes as to increase the likelihood of successful technology diffusion. The study identifies a significance of microcomputer playfulness as a behavioral input into innovation diffusion theory that has yet to be previously investigated from a technology adoption perspective.
