So which is better, a smartphone or a tablet? While it may be difficult to provide a definitive answer to this question, the comparison in this video provides valuable insight into how usability affects our everyday lives. As the video shows, sometimes how the product fits into your life is more important than user interfaces or a sleek design. Tablets may be more powerful than smartphones, but they’re not of much use if you can’t fit them in your pocket to carry around. This video is a great example of how usability is about designing a product to fit into and enhances the lives of its users. A good design will always put the needs of the user first and it will have a strong focus on practicality.
