Well, here's my use case.
I have a main job, it's mainly a bureaucratic job and I use company-issued computers at the office (Windows laptops, older i3 CPU, mechanical hard drives and 4GB of RAM, yes, it's as painful as it sounds).
I also have a side hustle, I've been doing this since December, I work in public relations, so I manage social media accounts, create promotional material and write press statements, for very small organizations, with very tight budgets so, for them, my non professional work is fine, also because I don't charge a lot (I want to change careers and you'll have to start somewhere, however my work is receiving praises from bigger names, I'm working hard to turn those praises into cash).
So, in all honesty, I don't really need Apple products.
What I need is a phone with a camera system capable enough to produce photos and videos that look (very) good on Facebook and Instagram and don't need editing, except for some minor tweaks in iOS' Photos app (I don't know jack about professional photo and video editing), I've tried using high end Android devices (Samsung S10 something and their last flip phone) and still don't like Android, can't find my way around it, way too many confusing settings, so my iPhone 14 Pro is great for what I do.
As for what I do on a computer (currently 2020 i5 MacBook Air with 8GB Ram and 256 SSD), I could get my stuff done even on any Linux distro using Libre Office if Iwanted or needed to, I could even try ChromeOS because I can use web-based services like Canva, Adobe Express and Office Web Apps, even though I don't particularly rely on those services, I look at Canva and Adobe Express only for inspiration (Microsoft Designer looks very promising too) so, for me, macOS, Windows or Linux wouldn't make much of a difference.
My 9th gen iPad is mostly an entertainment device (music, video, reading, web browsing).
However, I can say that using Apple products and relying on iCloud is somewhat making my life easier, especially AirDrop (I've tried Microsoft Edge's Drop feature, but it's not as smooth as AirDrop and it has stopped loading for some reason). I create material mostly in Keynote and Pages (they're surprisingly capable, even though I still don't find them as intuitive as I'd wish), the files are on my Mac and in iCloud, and it's very easy to do (small) changes to the files on my iPhone or iPad, if needed.
There's also the quality of the devices, my Mac has a great keyboard, great trackpad and great screen, this combination makes working long hours on the computer less tiring. One could argue that I could find the same quality in other premium laptops, yes, probably, but my main point is that I've created my own "work flow" using Apple hardware and software, this "work flow" is working very well for me and I don't see, at present time, any reason to change it.
