This study examined the effects of two main factors affecting microcomputer technology acceptance: perceived usefulness and perceived fun. We examined whether users are motivated to accept a new technology due to its usefulness or fun. Results of this study suggest that perceived usefulness is more influential than perceived fun in determining whether to accept or reject microcomputer technology. We also examined the impact of computer anxiety on acceptance. Results showed that computer anxiety had both direct and indirect effects on user acceptance of microcomputer technology, through perceived usefulness and fun. We also found attitude (satisfaction) to be less influential than perceived usefulness and fun. Implications for the design and acceptance of microcomputer technology and future research are discussed.
