On a daily basis, how many embedded devices do you rely on?

On a daily basis, we rely on more than 10 embedded devices, devices that have been programmed to handle a particular task, without realizing it. For example, almost everyone uses computer, watch TV, talk on the cell phone, depend on smoke detector for fires, use microwave to warm up the food, keep foods in refrigerator, listen to music on Ipod, use printer to print papers, use keyboard to type, use mouse to move the cursor, and use calculators to calculate numbers. As you can see, it is almost impossible to live without and function property without embedded devices. Some people might say we don't need those in our lives. However, people should know that the traffic light is an embedded device. Also, the electric generators are embedded devices.

Now the world and people depend more on embedded devices and can't live without it. The world creates electric from wind turbines, solar pannels and water turbine, which are all embedded devices, and people travel all over the world by airplanes, electric cars, and ships. The embedded devices are improving and developing as the time passes by and will be more useful to people.
