I have been using Linux as my primary OS for years now, and while it does 99% of what I need, there’s still the 1% that requires me to have dual boot.

Photoshop and another art software (Clip Studio Paint, for example) require Windows (or a Mac). I could probably get away with using Krita instead (and I do use it on Windows as well) but my drawing tablet (Huion display tablet) doesn’t work on Linux. Somebody wrote a set of scripts for it and it kinda works but you loose some functionality.

There is also the guitar amp & fx modeling software, plus a bunch of other audio softwares that may or may not have a counterpart on Linux. And I did try Wine with mixed results.

So, if you’re just browsing the internet or doing software development, you’re probably good and can migrate, otherwise, that article is maybe too miopic.
