A netbook, Internet-enabled and with extra portability, has been fast-growing in the domain of information technology (IT) in recent years. Compared with standardized laptops or desktop computers, a netbook's key features include a shrunken-down and lightweight laptop that is "easy to learn, easy to work, and easy to play". This research is to empirically test the influence of user perceptions of this new form of IT (usability, compatibility and relative advantage) associated with playfulness and attitude toward purchase intention. In addition, personal innovativeness of an individual plays an important role in the antecedents of such perceptions. A test of this model, two-stage approach, confirmatory factor analysis (CFA) and structural equation model (SEM) are employed to validate the casual model from among 227 usable respondents who have been using a laptop for more than two years. Results showed support for eleven of twelve research hypotheses, and one new path linking personal innovativeness with attitude toward using is found to be non-siznificant. 展开更多
