Bullshit. iPod touch, which was a low end model that followed iPhone, wiped out mp3 players, undone viability of portable game consoles, and roadkilled Windows CE, all without cellular just fine.
The iPod mini and then Nano had already taken out mo3 players except the cheap knockoffs before the iPhone. The original iPod Touch maxed out at 32GB and with that amount of storage, it was much more expensive than most MP3 players
Apple launched in a market with comprehensive cellular coverage.
The charging stations grid is still being built out, so Tesla was in a completely different situation circa 2013.
