A smartphone has a pretty defined purpose: communication. It's powerful and generic enough to be a general purpose computing device, sure, but the vast majority of users use it to do just that: make calls, send messages (whether via traditional SMS or social media offerings). It has some secondary usage such as internet browsing (primarily consuming streamed content, these days) and photography (largely for messaging/social media purposes). Occasionally it might be used for something more heavy duty, like some light editing of photos and videos. Some people play games on it. But it's still oriented around being a communication device. There isn't much difference between that and a modern gaming console (apart from the orientation being around games/interactive entertainment). Take my PS4, for example: beyond the games there's pretty capable light photo and video editing software, a web browser (based on Webkit, actually, and has a surprisingly pleasant and minimal UI/UX even when using just the controller and not an external keyboard and mouse), a ton of content apps (Netflix, Disney+, Spotify, YouTube, DAZN, etc) as well as Twitch and the Playstation Network platform (essentially social media). In my opinion the only thing holding it back from gaining more apps and completely eating up the lower end of the desktop market is that developing apps for it is prohibitively expensive (gotta order a dev kit). Even at that I still plan to keep it around as a very light desktop alternative when I replace it with the next generation.
