Windows is not perfect but it excels in many regards nowadays and the last years, Macs were really expensive and risky. They were too expensive to just have a fall-back machine lying around (if you make serious money with you gear, every hour counts). I have 3x 2.5lb notebooks here, if one needs to be sent in, so what.
Edit: just opened it but there are no ads... what do you mean?
What I don't understand about this, however, are people being paranoid about W10 while they're happily accepting Google and friends to infiltrate their lives ¯\_(ツ)_/¯
You are of course exempt if you don't use any cloud-based services that you don't host yourself :D
That stuff also has a nasty tendency to ""accidentally"" get re-enabled after updates from many reports I've heard.
A new Windows install requires at least an hour of de-cluttering and shit removal, while for a new Mac full setup to my liking takes about 5-10 minutes and I generally don't have to uninstall much of anything. The only thing I sometimes remove are apps I never personally use like Garage Band to save a bit of disk space, and that takes like ten seconds.
Then there's the almost Android level of obviously spyware telemetry going on. Yes I know Apple has telemetry but I trust them quite a bit more than Microsoft both not to do anything deliberately sketchy with my data and to be competent with their security. They also do a lot less and a lot less invasive telemetry. Redirecting local search, sending file list dumps, etc. to the mothership is unforgivable unless I have explicitly opted into that kind of behavior e.g. for tech support or debugging. That's the kind of stuff I associate with borderline malware, not an OS by a supposedly reputable company that I paid for.
Microsoft's recent behavior is pegging them in the low end of the market and ceding the high end of the market to Apple. Then of course there's Linux. If Apple did something barking stupid that forced me to ditch the platform that's where I'd go. I'd miss the Apple degree of trouble-free operation but at least I'd keep my privacy and security and lack of foistware.
"Ceding high end of the market to Apple". I would not go into much details but for example my gaming grade laptop runs circles around Mac that costs twice as much. So sure I'd rather be a "low end" peon with the decent hardware.
