"People are increasingly using their smartphones for everything.

"People are increasingly using their smartphones for everything.

They do it mostly through apps, and in particular social and messaging apps, such as Facebook, WhatsApp, Snapchat, and Twitter.

The competition to become such an app is intense. Competitive advantage for platforms relies on being able to keep your users within an app. The more your users are within your app, the more you know about them, the more that information can then be used to sell advertising, the higher your revenues."

I think this might be true to a certain degree, but I think it over estimates the use of smart phones. I don't use my smartphone for everything. In fact I mostly use it for phoning people and keeping track of the time. But then, I might be that exception to the rule here. See I prefer ways of TURNING STUFF OFF, which I see is difficult with regular use of apps on smartphones. For me they're difficult to read and error prone in use. I prefer desktops, and mostly the ones I have at home.

So, I think the assumption that everyone uses smartphones, and uses them  the same way, is very short sighted. Trouble is, opinions like mine probably won't be seen, because it's not sent by an app.
