There is a lot of debate about whether wearable computers, such as smartwatches, will be successful. However, in this paper, we will review the existing literature on smartwatches and discuss their potential advantages and disadvantages. We will also discuss a study that is, to the best of our knowledge, the first to investigate why and how people use smartwatches in their everyday lives. We will also highlight the added value that users see in smartwatches, and identify some limitations to their widespread use. The history of online shopping can be divided into two parts: the early days when it was used just as a way to advertise products, and more modern times when people started using the Internet to buy things. This happened because online pages became more interactive and secure, which made it easier for people to buy things. Wearable computers are devices that are designed to provide useful services while the user is performing other tasks. Some wearable computers, such as wrist-worn devices, are commercial and are used by people for various purposes, such as tracking their activity and health. However, wearable computers as a whole have not yet lived up to expectations. Many people were expecting wearable computers to revolutionize how we use technology, but they have not yet done so. The smartwatch market is worth $17 billion in 2019 and is predicted to grow to $64 billion by 2030. This growth is primarily due to the addition of features such as cellular connectivity, health and fitness monitoring, and interoperability with other connected devices. However, if smartwatches are to become indispensable to consumers, they will need a killer use case. It’s a future Tech friend for everyone its trends show the same for the future.
