I beleive the iphone is one of the greatest innovations. For starters the iphone was the first hand held computer, it included web browser, email, music and applications. We use our phones everyday and the iphone makes your day easier by including a calender and being able to add events to the calender, having a calculator built in, a notepad, camera and weather service! The iphone provided 24/7 internet aswell wich made communication around the world always happening. Lastly it only has a home button and the touch screen is one of the best on phones.
