The rapid proliferation of smart gadgets—encompassing smartphones, smart wearables, smart home devices, tablets, and Internet of Things (IoT)-enabled consumer electronics—has fundamentally reshaped consumer markets and purchasing behavior across the globe. This article examines the multifaceted dimensions of consumer behaviour towards smart gadgets, integrating theoretical frameworks, empirical research findings, and contemporary market trends to provide a comprehensive analysis of the factors that drive, moderate, and constrain consumer adoption decisions. Drawing upon established models including the Technology Acceptance Model (TAM), the Unified Theory of Acceptance and Use of Technology (UTAUT), and the Theory of Planned Behaviour (TPB), the article investigates the roles of perceived usefulness, ease of use, social influence, hedonic motivation, price sensitivity, brand perception, and post-purchase satisfaction in shaping consumer attitudes and purchase intentions toward smart gadgets. The study further explores emerging behavioral patterns related to brand loyalty, switching behavior, online versus offline purchase preferences, and the growing influence of digital peer networks and social media on consumption decisions. Key challenges including privacy concerns, technological anxiety, information overload, and rapid product obsolescence are critically examined. The article concludes by proposing a conceptual model of smart gadget consumer behaviour and offering strategic insights for marketers, product developers, and policymakers operating in the smart technology ecosystem.
