Speculating from a single anecdote, I have a nontechnical friend that switched to using a smartphone instead of a PC. Part of it is that the smartphone can do everything they need from a computer. Browsing the internet, messaging and email, etc. But that answer alone isn't very satisfying, because even when doing nontechnical stuff on a smartphone, like browsing reddit or watching youtube, I find it very inconvenient compared to a desktop. I think the real reason is, when she needed to use her computer for something, it took 15 minutes to start up. That's super inconvenient. People talk about how small 15 second delays can discourage behavior and cause frustration. 15 minutes is just ridiculous, and really discourages using the thing unless you really need to. I installed a pure copy of windows 7 on an old computer recently. Nothing installed on it at all, no connection to the internet, nothing put on it by the manufacturer. And the specs weren't that good. Yet it took 30 seconds to boot up. I was amazed, I didn't think that was possible for a modern PC. Even my phone takes longer to boot up.
