You mean everyone copied the LG prada or any of the early HTC models with a full touchscreen.. there u go, I fixed it for u.. let's not get the facts in the way of a good story eh..
here we go again...
the iPhone was a leapfrog product.. yes, it didnt invent one particular thing (there were other phones that had a chrome trim, and there were other phones with a big screen, as you'd pointed out).
but none did it with the refined look and feel that the iphone has, alongside its capabilities and
combined features (accelerometer, proximity sensor, capacitive multitouch screen, robust, Unix operating system, solid industrial design, glass screen)
Otherwise, the LG prada would have been the phone to beat in 2007. and it wasnt.
Everyone's strategy shifted to catch up and match the iphone after 2007. Because it was, as a product of
aggregate qualities, ahead of the pack. there was a picture that's widely circulated, Samsung phones before the iphone, and samsung phones after the iphone, the differences were definitely not subtle. iPhone had a distinct look and feel.
