The only way you could ever get me to use Windows as my daily driver would be if you paid me a significant amount of money, or you smashed all my Mac hardware.
Even if I disregard the privacy concerns of Windows 10 and the constant updates that interrupt me, for my personal needs Windows is just not as good of a development OS as macOS is. I do concede that the way I laid out my development environment is unique to me, so it's an issue of my own making, but it works for me.
(If you're curious, the issue is that I use symlinks quite extensively for my vB3/vB4/XF1 work, and symlink support / stability in Windows leaves something to be desired.)
The fact that I own an iPhone and thus have the ability to text / make calls via my desktop is also a huge boon.
However, the biggest factor that makes me prefer Macs, is how long they actually last. I am currently using an entry-level 2012 Mac Mini (2.5 GHz Dual-Core i5-3210M), which I bought for £500 ($640). I've since put about £200 ($255) worth of upgrades into it (16 GB RAM, 250 GB SSD). It works perfectly as a web development machine and general web browsing machine. I have no serious complaints about the speed of it.
I challenge you to find me a Windows computer that cost £500 in 2012 that you can put £200 worth of upgrades in and have it work
this well in 2018 - especially when you consider the form factor. Furthermore, I challenge you to attempt to sell that computer for £200+ in 2018.
I'm going to go out on a limb and say no-one can meet either of those challenges.
If you want an all-in-one device that can do work, leisure and gaming, then don't buy a Mac. Even if you buy the most expensive Mac Pro and push the specs up to the £10,000+ price range, it's going to get destroyed by a £1,000 Windows PC for gaming.
If you want a work / general browsing machine, and you're willing to accept that you are not going to play any games on it, then unless you are on an extremely tight budget, buy a Mac. It will retain both speed and value
way past what a Windows machine could ever hope to achieve.
Edit: Oh, and I forgot to add that we are now living in a bizarro world where Macs have better plug-and-play support for legacy hardware than Windows does.
I can plug my laser printer/scanner combo from 2011 into a Windows computer and it will refuse to work because drivers don't exist anymore, but when I plugged it into my Mac mini saw macOS install drivers automatically from Apple via the App Store. After installation, the printer was identified correctly in the Printers & Scanners preference pane in macOS (i.e. as the actual make & model, not just as "generic printer").
