With laptops, you can easily take your work with you. Computers can do things that phones, tablets, desktops, and even TVs can't do. Computers literally have a role in every career field, educational field, medical field, industrial field, banking and financial field, in the government, they're everywhere! In the educational field, students may be home-schooled with programs that require a computer. In the work field, people may work from home or need a computer to look up files that they may not have documented on paper. Anyone can see that computers are very useful in life, a lot of people rely on computers for their well-being financially and educationally.
Hope this helped!
