alt Hacker NewsI have switched from Windows completely to Linux more than 20 years ago, after a few years of dual-booting.
The moment when I could ditch Windows was when I got on Linux several video-related programs, e.g. a DVD player and a program that could use my TV tuner. For all other applications I had already switched to Linux earlier. Those other applications included MS Office, which at that time I continued to use, but I was using it on Linux under CrossOver, where it worked much better than on the contemporaneous Windows XP (!!). The switch to Linux was not free as in beer, because I was using some programs that I had purchased, e.g. MS Office Professional and CrossOver (which is an improved version of Wine, guaranteed to work with certain commercial programs). I did the switch not to save money, but to be able to do things that are awkward or impossible on Windows.
I do all the things that you mention, and many others, on various desktops and laptops with Linux. I do not doubt that there may be Linux distributions where you may have difficulties in combining very different kinds of applications. However, there certainly also exist distributions without such problems.
For instance, I am using Gentoo Linux, precisely because it allows an extreme customization, I really can combine any kinds of applications with minimal problems, even in most cases when they stupidly insist to use dynamic libraries of a certain version, with each application wanting a different version.
As another example, I am using XFCE as a graphic desktop environment, because it provides only the strictly necessary functions and it allows me to easily combine otherwise conflicting applications, e.g. Gnome applications with KDE applications.
XFCE is actually a great example of the problem with Linux
It's wayland support is utterly broken right now and getting very little attention. The major distros are about to put X11 in the grave and then XFCE will die (or more likely it'll live on in some weird offshoot distro).
That's not really an acceptable situation for a consumer product.
now obviously xfce is not one of the main DEs pushed by the distros, but it's plight is a symptom of a couple of problems that plague linux
Compatibility is important. MSFT, for all their faults, puts a shitload of effort into making sure that even old ass software keeps working. They're not perfect (especially in the last few years) but they're miles ahead of linux here. As a user, I shouldn't ever have to know or care about wayland or pipewire or whatever other nonsense, but that's not the case. I have to know just so I can find software that works with my system.
