That is about 3 months since I made my last attempt at switching off my macOS devices and I am in a similar place as you, I use Windows predominately now. I turn to my MacBook only when I need something portable.
Very happy now on Windows, they all have their place and opinions vary of course but I choose what works best and that is not just Windows, but the hardware too.
I will get an ARM laptop if the thermals are better, battery longer and Apple don't completely screw it up. That seems to be the sweet spot for me these days. PC for most of what I do, MacBook for when I need portability or a task that I would get more out of on macOS.
Same here. I'm using my AMD desktop primarily now and my MacBook Pro sits off the side. Helps that most people I know, including my work - use iMessage so I have to have my iPad up or my MBP up at all times to answer texts.
But I game a handful of times throughout the week and switching between my MBP and my desktop with my one monitor got old REALLY fast. I want to give away or sell my MBP but I know the instant I do I'd want another one.
There is no perfect device. I'm resigned to using a handful of them as tools. A toolbox does not have one tool to be effective, it has a variety because when you need that one tool you haven't used in forever, you're up a stream without a...
I spend enough $ on iPhone and iPad Pros, I don't see myself tossing $ at another MBP again. Maybe a low end Air when on sale at Costco?
My $1500 AMD Desktop is still screaming, Windows 10 is acceptable, and with the ability to upgrade, I see 5-10 years of usage as something easily done. However, the moment they call us back to the office... my view on that will change, but I have pretty much decided to keep the desktop.
I took it apart after a handful of months of ownership and found that the case has dust screens and .... they were almost completely impacted. Ooops! Didn't even know the case had them, lol. Guess I'm going to be dusting every few months.
