I think that the best technology invented in the last 20 years is the cell phone. It is one of the most used inventions in today's communication world. The cell phone has changed people's lives and has changed the way that we think. People can now text a friend instead of paging or calling . People don't have to set times to meet any more because texting is so much easier and more convenient. The cell phone is now a great way for business people to get a hold of their clients while they are on the run. It also helps them by letting them send a picture of what they are doing on the job site. Cell phones are a fast and efficient way to search for information on the Internet. Today kids and adults alike use them for communication but in the future who knows what they will be able to do.
