Windows exclusive apps with which i revive bricked usb flash drives and devices, for example, can you find flashing software (not fastboot/adb suite) with which you can revive completely bricked android devices on speedtrum cpus or unisoc cpus or other noname cpus, windows have a lot of specific software that wine cannot handle and virtualbox handling very poorly, I've heard many science software (abandonware) still requires windows xp and 95/98 and running in many labs out there (p.s I've been daily driving Linux for almost 9 years already but still recognise that windows won't disappear because we NEED to use that abandonware because there's simple no equivalent on Linux and never will be because many on Linux scene despise old software and some of people despise old hardware with that, I've experienced such people in comments of lemmy already)

The two most important things missing from Linux are mass familiarity and certain important professional software suites. It isn't that Linux doesn't have software nearly-equivalent to things like the Adobe suite, MS Office, and AutoCAD. It is that it doesn't have those EXACT applications. Like it or not, in a professional setting, you usually have to use the big proprietary applications because that's what everyone else uses. Using standard software reduces compatibility and training headaches, and eases recruitment. Most technically-oriented professionals wouldn't even take a job that disallowed them from accessing and maintaining their competence with the standard software of their profession.

AutoCAD/solidworks

My art software, 99% of music software/plugins. Other than that, I'd be good to move to Linux. I've been dual booting for years now. But Linux isn't for everyone. There's a lot of stuff missing, and when everything works it's great. But troubleshooting isn't a slope of problems that increases gradually in the difficulty, it's actually a cliff.
