Remember that MP3 players were not Apple's idea. They built the iPod and created the digital music marketplace for the mainstream. If the image you posted is analogous to the iPhone. Then this image is analogous to the iPod:

So many wrong things in this post, but I'll just bring out one.
Not tied to a carrier? You do know that the iPhone was an AT&T EXCLUSIVE for quite some time, right?
