I just have to wonder ... was this designed to solve some problem
Ahem, when was the iPhone ever designed to solve a problem. Apple needs to stick a LASER projector synced to wireless LCD shutter glasses into the iPad along with a theremin attachment. Now that would be cool.
It actually was. The smartphone market was well established but mostly business oriented. The iphone took smartphones to the consumer market by making it geared more toward multimedia. Despite Apple's claim it wasn't innovative at all, phones had been out for a few years already which could do everything the iphone did but they just weren't marketed that way so not many people bought them other than corporate types so they could have their e-mail on the go. I had a touchscreen in 1999, was playing mp3's through a cassette adapter, etc,.
