Computers (paragraph writing exercise)

Computers, which are useful and very popular, are nearly ubiquitous in fooices and in the home and are effective time-saving devices. However, they are only a tool and are therefore only as effective as the people who use them. It must be remembered that they must be used for the purposes for which they are designed, but they can be misused and this can cause them to be more of a hindrance than a help.
