Not sure about the downvotes, but talking about the influence of who buys personal computing devices, almost no-one cares about the above. Cloud stuff disappears? You open up somewhere else and mobile devices are fine computers/computing devices. Almost no-one who is non-tech is buying laptops. And those are the same people who don't care about 'your data', data privacy and all that. They read about it in the paper, have no clue how it affects them and then start up Facebook and forget about it. And that's 30+ers. Kids < 20 really don't care about any of that. My cousins drop their tablet while playing and just open another Gmail account because they cannot be bothered to write down the password. And they do everything on those things.

Unless you're talking CAD/CAM, game dev, 3D modelling, movie/music editing, sci computing, people are simply not buying laptops proving mobile devices are great computers for 99% of the world. Oh yeah; they don't care about the OS either; they care about what 'others' in their situation have; they buy what their friends have or what looks good when sitting at the hairdresser.
