> What do you mean by that? Smartphones had been around for years (e.g. devices like the SE P800 and P900 series) before the iPhone, but these remained niche and required specially skinned websites for full functionality (XHTML and CSS stylesheets with `medium="handheld"`, which is now dead). It was really the iPhone's capability to render normal websites and to navigate them via pinch & zoom, which was considered the killer-app of the iPhone (esp. before there was an App Store with a wide variety of apps available.) The success of the iPhone was built on the much acclaimed multi-touch feature. And this is now, with responsive web-pages set to `meta name="viewport" content="width=device-width, initial-scale=1"` as a standard, practically disabled and dead. (In other words, with a grain of salt, responsive killed multi-touch – or, at least, rendered it disposable.) (Moreover, I do not see any wide deployment of two or three finger gestures or similar multi-touch interaction on usual web-apps, especially, as these lack any standardization, but this may be just my own observation and anecdotal. That said, there's probably a niche use for virtual controllers for web games. But it's really the Mac trackpad and maybe the Magic Mouse, where multi-touch lives on with any significance.)
