Iphone's have revolutionized the way we communicate it seems 
I agree. Amazing to think the first gen was released in 2007. It seems like just yesterday.
Time is moving so fast! I remember when they didn't exist at all
Yeah and I remember when cell phones were the size of a brick, lol. iPhones run Apple's iOS mobile operating system.
They are the main competitor with Android devices
That is true and Apple's App Store has more than 2 million applications available for download.
Wow, I didn't realize it had so many now
The App Store opened on July 10, 2008 with only 500 apps available. It sure has grown since then!
Apple is the most profitable organization in the world, I believe
Their headquarters are in Cupertino, California. They have revolutionized computing and smartphone design.
