You are not the target audience for Microsoft, the corporation is. Who uses a home computer anymore? (it's all smart phones now) You start work, you get a pre-installed Windows laptop to use by the corporate IT department, configured to be used as they see fit. You no longer own a computer. Nobody is expected to, these days.
Me (but not Windows), my three grown children, my sister, at least one brother in law. At least half of the people I know personally. Half of them using laptops, the rest desktop machines. All of them have smartphones, and sometimes tablets, as well.
I think combining Macbooks and gaming PCs then home computers are being used more than ever, but I'm not sure, it's true that you don't need one to browse facebook anymore. But at the same time I don't know anyone without a laptop.
