Here's a blog post arguing that the iPhone wasn't disruptive, like PC vs mainframe - the PC was worse in every respect, but it was also dramatically cheaper.

Instead, it was obsoletive, like PC vs typewriters - the PC was way more expensive, but could do so much more, and once you had a PC it didn't make much sense to have a typewriter too.
