Haven't regretted it once.
The machine I built for half the price of the equivalent Mac STILL makes me feel all warm and happy a year later. It feels weird to have more performance than I'd ever need, while spending so little. Windows 10 is perfectly usable, unlike multiple predecessors. WSL is amazing, and basically gives you that *nix-terminal-in-an-instance feel that used to be a unique feature of OSX.
It's easier than ever to switch, and there's less reasons than ever not to. Apple is treading dangerous waters I reckon. I seriously think if more Apple users knew how far Windows PCs had come, they'd be switching now, as I know I myself held off for a fair while just because I was hesitant to believe it had gotten that much better.
