     Hightech machines have made life easier for millions around the world. However, some people still

prefer lowtech ways of doing things. Here's an example of why this is happening. You can microwave a

frozen hamburger in 60 seconds. However, it won't taste as good as the one you cook on the stove. And if you're in that much of a hurry, you probably won't take time to toast the bun.  Hightech cooking saves

time, but it doesn't make bettertasting meals.

     Most people get their news from hightech sources like television or the Internet. This has many

advantages. For example, electronic news is more up to date than newspapers or magazines. It's also more exciting to see live and videotaped news events than photographs. However, newspapers and magazines

have some important advantages. They give more background and details. They also let you read the parts that are important to you and skip the rest.

     Other hightech timesavers have similar disadvantages. For example, most people use the phone or

email to stay in touch with friends and family members who live in other places. But when you use the

Internet or the phone, you don't always think carefully about what you are saying, and sometimes you

forget the important things you want to communicate. Similarly, when you wordprocess a homework

assignment instead of handwriting it, you can check your spelling electronically and put in fancy headins.  

However, some students are so busy with the computer that they don't pay enough attention to the

actual words they are writing.
