Smartphones have evolved greatly since their introduction in 1993. They now offer full computing and internet capabilities comparable to laptops. While smartphones provide advantages like constant connectivity and access to educational tools, they can also enable anti-social behaviors if overused and pose security risks. Research shows smartphones are widely used in South African businesses but can blur work-life boundaries if not managed properly. Overall, smartphones permeate many aspects of modern life and can have either positive or negative impacts depending on how they are used.
