PCs provide a richer experience especially for the tasks that require focus and productivity too. Phones are just ideal for brief and a kind of on-the-go activities.
I've been using Windows 11 since April last year and personally really like it. I used Windows 10 before that, and considered it Microsoft's best OS to date. But that's just me. 😀
You like upgrading and I love that. I can use all the windows both 7, 10 or 11 but I found it uneasy when I start looking for something in other windows that I know where they are in window 7.
