Remember when Flash was considered so necessary, that when the iPhone debuted without it, Walt Mossberg himself wrote articles claiming inside info that Apple was going to soon include it with an iPhone update?
Remember early iPhone demos where Jobs showed stored versions of popular websites, which had been intentionally modified by Apple developers to hide the fact that the iPhone could not show the Flash content? This was because he wanted to claim that it showed the "real internet", which was a baldfaced lie at the time.
My favorite was when they stuck in a fake photo not only to hide a missing Flash menu in the middle of the National Geographic website... but also to "prove" how much faster the iPhone loaded "real" webpages.

Upper left is the faked site he demoed. Right and bottom were the actual site. I think he did the same with the NYTimes site.
By the time tablets became popular, Flash on Android was stable and fast.
My youngest daughter only used Android tablets for years because the best pre-teen kid's interactive games of the time were written in Flash and were not available on the iPad.
Now she uses a Mac and iPhone, but back then she refused to touch them.
