Re: Even happier I chose a PS4
It's all about stats and habits.
* They know your age, location and language.
* They know what you play.
* How long you play.
* They know from where you play. Wifi, Cabled , therefore probably also know your ISP.
* They know how many games you possess and what genres you prefer.
* They can see the evolution of what you are buying, playing, winning losing.
* They can see what music, films, media you like to watch, buy, download.
* etc etc etc
Sony can learn a lot about you even through a simple games console. And that's only the stats that I can imagine, they might have much more sophisticated algorithms... "Shaky wrist" detection for example..
