Sadly, a lot of people (generally die-hard nerd types) genuinely believe that marketing was the sole reason for the iPhone's meteoric rise in 2007. They don't place any importance on user experience and therefore can't tell the difference between the iPhone and the early-gen smartphone predecessors (Palm/Nokia/etc).

These are the same people that are now confused as to why Slack has risen in popularity despite the existence of IRC, which (in their eyes) is technically superior.
