You're absolutely not the only one.
For most of my life I have been a Windows and Linux user -- often dual-booting. To be honest, for many years I couldn't afford anything Apple, but I could afford an x86 PC that I could build myself to get the best gaming performance. So I would do so, oscillating back and forth between Windows and Linux as practicality and purity warred in my technical needs.
Eventually I did buy an iMac for a separate office outside of my home study. And then eventually it just got me. Eventually everything in our house just got converted to Apple.
The reason? You get Unix underneath, but the user interface broadly works and all the software you want is there. Apple things don't break very often. Plus, there are synergies between the iPhone, iPad, iMac, MacBook etc. Sure, there are many, many Apple annoyances, but eventually it just makes sense if you are mainly creating and consuming content rather than having the time to tinker.
The only Windows machine left in our household is our loungeroom Dell media centre. And it is going to get replaced with a Mac Mini shortly. Why? Space reasons, but also because -- just like you -- I saw that icon pop up on the dashboard pushing Windows 10.
I went ... hell no. I want control over my operating system. And right there and then I resolved to ditch Windows and move that last machine to OS X eventually. The spying stuff tied to the Start Menu and so on that Arstechnica exposed also made the decision easier.
I would actually go all Linux if I could -- just to get out of all these companies' ecosystems. I have in the past. But with a family and a small business, it just makes more sense to continue to put up with Apple's little foibles. I don't have the time to tinker anymore.
Having said all this ... Windows still makes 100% sense for most corporations. Apple + Linux are just not aimed at providing desktop environments for more large organisations. It's a great product for that environment. That is where I think Windows has its strengths. But not in the consumer/small business market any more.
