“Also, the need for a music player created the Ipod which in turn created the Iphone.”
No, it didn’t, SOMEONE created the ipod in response to a PERCEIVED need but need has never created anything and the Ipod certainly did NOT create the Iphone. All the needing that I have ever experienced did not create so much as a crumb.
It is not a coincidence that the Iphone looked similar to the ipod. Heck, the ipod and ipad are very similar in form-fit. The iphone/ipad is an ipod/basic ipad with the telephone electronics. That is how Apple markets the product family. Both have wifi, both play all of the apps. The only difference: the telephone electronics.
Plus, I bet that one of the decisions many folks make when buying an iphone is “does it play my thousands of dollars of iTunes music.” The answer is yes and it is no coincidence.
