biggest advancement in technology

I think the biggest advancement in technology is the cell phone. It has made the largest impact on our society. I can't imagine life without cell phones anymore. They're everywhere, and almost everyone has them. You can now call anyone, anywhere, at anytime. Our society has advanced the number of features with the cell phone. Features such as MP3 players, cameras, and even the internet come with a lot of phones. Cell phones are also a big part of our economy. Many people make money working in cell phone companies or selling cell phones at a litle booth in the mall. Cell phones have definetely made our life easier.
