This empirical study applies the structural equation model to test hypotheses about the adoption of PDA phones from a consumer perspective. It finds that adoption and purchase intentions are distinct from each other and have different antecedents. While perceived usefulness and enjoyment have more significant effects on adoption intention, perceived risk and cost have more significant effects on purchase intention. The adoption intention widely used in TAM studies does not fully explain a consumer's adoption behaviour. The results of this paper extend TAM studies and offer more insight into a consumer's adoption behaviour regarding ICT products.
