What things did the first Iphone have that other phones did'nt?

Like what attracted people to the Apple Iphones?

A touch screen, camera, 3G, an appealing look, music, few apps. Just the idea that it was a phone made by apple.

A multitouch display
A full HTML5 browser
iTunes access
Google Maps
built in iPod
etc

The first iPhone had the honor of being distinguished as the first true "smartphone" most popular phones back in the day were still keyboard based and other touchscreen phones bieng made at the time were complete garbage, the iPhone was also an iPod which were really big, it also began to introduce the concept of apps, it also introduced the first successful internet browser, it was just a complete breakthrough in mobile technology, and just the fact that it was made by apple made it so big because they were really expensive, I remember in school if you had the iPhone you were considered "cool"
