The ever-increasing functionality of today’s software applications comes in tandem with added complexity, which may hinder elderly citizens’ full participation in the digital world. Building upon Van Slyke et al’s (2004) extension to TAM, the authors explicate the relationships between software functionality/complexity and users’ perceived usefulness and ease-of-use of software. The influence of age difference on these relationships is also examined.
