Rapid developments in information system (IS) have changed the nature of products and services, and proving a useful accessibility to consumers. In line with the technological changes above, major research streams in IS discipline have continued interests in understanding individual acceptance and their IT usage. Aligned with the emerging interests, the current study attempts to investigate the antecedents of user’s technology acceptance and their satisfaction towards digital products and services on the basis of the sound theory - Technology Acceptance Model (TAM). Therefore, two studies are created for this purpose, including user’s adoption towards e-textbook as well as satisfaction and purchase intention in the use of App, respectively. The first study aims to propose and verify an extended TAM to understand the antecedents of user’s adoption in the use of e-textbook. Based on the empirical findings, we concluded that our proposed model incorporated with perceived enjoyment is more suitable to predict user’s adoption of e-textbooks than the original model, indicating a way to enhance customer’s positive attitude towards e-textbook. The second study integrated the TAM and Expectation-Confirmation Theory (ECT) for IS continuance to explore antecedents of satisfaction and purchase intention towards App usage. Findings included: (1) All three antecedents of App satisfaction, perceived usefulness, enjoyment, and social image, were confirmed. (2) Perceived usefulness and social image successfully predicted the purchase intention of App. The findings demonstrated a fact that end-users much concerned with whether the use of App can improve their self-concept and images among others than with other utility concern. Further discussions from the two surveys are provided.
