21st century invention

The invention I chose is probably one of the most important inventions of the 21^st Century: the IPhone. It was released in 2007, and changed completely the way in which mobile devices are used. The older mobile devices that already existed inspired this invention. Not all of the older devices had a keyboard to send messages, screens were too small and so texts were difficult to read, and the structure of the device made it difficult for someone to execute different actions on the phone. I believe all of those negative things led to the creation of a phone were a big and touch screen allow users to execute different tasks easily, and the keyboard allows people to send text messages. In addition to these, the IPhone can have other purposes, such as music player, photo and video camera, entertainment item, and more. As the years go by, Apple adds new things to the IPhone that will definitely lead to new inventions in a future. I think that one invention that actually came out from the IPhone is the IPad, which is a mobile device similar to the IPhone. I definitely believe that the IPhone will inspire more new and peculiar gadgets/devices.
