I Can't Be Bothered To Completely Migrate Off Windows
Linux has been my main operating system of choice for many years now. On the other hand, for many practical aspects, I still have to keep an Windows installation around.
Let me enumerate the pain points:
For Brazil's annual tax income report, only the desktop version of the application is fully-featured. I already don't enjoy any minute spent there and I definitively don't want to spend any additional time figuring out Linux corner cases. Just boot up Windows, download this year's application, fill in the forms, submit, and be done for this year.
At least two of the Brazilian banks I use require you to install “security modules” in your computer to access your bank account from a desktop. Guess what is the second scenario I don't want to spend one minute and I'd rather just boot up Windows? I've tried having just Windows VM running on Azure for this purpose, but that quickly turned into having my account blocked and having to do a trip to the branch in person to unblock my account for home access.
(As an aside, I like to play StarCraft II on my personal time and I've put up with at least a year of working around Wine/Proton issues so that I could game on my main computer while on Linux. You know what doesn't require me to spend an afternoon or morning before I can play? Yeah, a fresh installation of Windows.)
Finally, the Office suite is still the de facto standard for many context when you have to work together with other people, be it in academic/university contexts, in professional contexts, and so on. Again, there's no use and no joy in spending time figuring out LibreOffice or Linux weirdness when every technical challenge can go away by just booting up Windows, launching Word/Excel/PowerPoint with no surprises, then finishing the work and being done with it.
It's no question that the Web and open formats have since a few decades ago made huge progress, especially elsewhere.
I've used First Tech as my bank in the US and TD Bank while in Canada, and neither have required me to install anything in my computer to have access to home banking.
In Canada, filing taxes with the CRA has been completely through the browser, no installation required or operating system was assumed. (Indeed, multiple vendors provided competing web-based products to file your taxes and optimise your deduction claims, instead of the federally-mandated single software solution as in Brazil).
Nevertheless, the world is as the world is, and I'd rather consider Linux an additional tool to be in my toolbox. I'd like the whole world -- especially governmental and financial institutions, as crucial as they are -- to move out of proprietary formats, but such is not the case for world we live in.
To be honest, I can already imagine blank stares, asking themselves exactly why moving out of proprietary formats and systems would be something important to do at all given that the existing solutions we have “just work”.
Let me consider this a “lost cause” for now and re-evaluate in 10 years whether a complete jump to Linux for all my main computing needs would be feasible by then.
Regardless, let me keep all my primary copy of my files tidily into the file system, not solely in cloud services.
