I'm taking a speech class for an easy credit and we have to give an informative speech. I chose to do mine on the advancement of technology, specifically, the apple iPhone. I have to pick 2-5 main points. For each point i am going to choose an application, but i'm not sure which are the 'most' revolutionary. If you could just suggest an application and why you would choose it, i would be much appreciative. Let me know too if you think this is completely pointless, and i'll delete it. Thanks!
