Linux

• Better battery life.
• Cmd based hot keys for cut, copy, paste and close. They don't collide with others as much, particularly vim based keys.

Some of my steam games dont run, and theres some files I cant run in Davinci Resolve. So probably just those

Knowing how to fix my wife's computer, or my parents' computers, or my brother's.

Actually, while it's rather frustrating for them, it's not so bad for me ;-)

installing programs. there's been random programs I've needed to download for school and I've sometimes spent hours running into random errors, having to find out what library or dependency I'm missing, etc. I miss being able to just click on an .exe and that's it.

One of the only things I miss from winblows is how I can download an exe or msi installation file and just install.

I mean, I do enjoy getting things installed via cli through a repository, but I suck at installing from source for those things that don't have a deb installer or an appimage or something similar.

Otherwise, not much right now other than the fact I cannot figure out how to get the headphone jack to work on my laptop (galaxy book 3), leading to me having to use bluetooth headphones and my OS sometimes deciding I don't need the high fidelity audio profile options, making everything sound like ass.

Coming from Windows I miss the excitement and suspense of never knowing whether my click on an icon actually got noticed by the OS. And the thrill of never knowing exactly which icon you clicked on because the UI is so slow to draw and redraw itself that the icons move unexpectedly while you're aiming. Oh, and the unpredictable surprise of focus stealing.

I moved to Linux over 25 years ago and I miss absolutely nothing.

The joy of not having to update your OS when Microsoft forces it, even whilst you're working, or the way Apple still cannot do window tiling despite decades of examples on how to achieve this, or installing applications and finding files splattered all over the file system with no way to remove them except manually, or the endless user agreements, licence fees, expiring licensees, or the notion that you cannot run a new OS on an old machine that's in perfect working order.

So, no, it was the best decision I've made.

I wish that I'd made the same good decision when it comes to my accounting software.

Being able to play League of Legends. We could until few months ago.

Not a darn thing.

I don't miss anything really. All of my software already worked.

• Prepare for a shock, I miss... Apple Notes.
  Like, really. Imho it's a great note-taking app that is also performing really well even on large number of notes, that also natively syncs between the Mac and iOS, with full-encryption. It's also an app that, well, does not expect its user to become an engineer and/or a dev unlike some certain others text editors out there ;)
• The other one basic app I do miss is Apple Photos.
  Like with Notes, I miss its simplicity while still including those very few more advanced features an amateur and very occasional photographer like myself seldom needed access to. Sure, there are excellent Libre alternatives, much more powerful and more complete, but they are all also much more clunky and complex to use which make it so that I use them a lot less than I used to use Apple Photos.
• Pixelmator Pro, for the even fewer more advanced photo edits I need. Here too, we have Libre alternatives but I have yet to find a one that is as intuitive to use as Pixelmator is.
• Affinity Designer. Inkscape is on its way to replace Designer for me, that's one thing.
• My spell checker/dictionaries/grammatical guides, for French and English: Antidote.
  It used to run offline (no Internet required) on Linux, on Mac and Windows, and I happily paid for its license to be able to do so. But the latest version has dropped its support for Linux, unless one is willing to use the coud version, which I'm not.

All those apps are very different but they share one thing: they are not complex and unintuitive apps (I reckon it's at this point I should get flamed to death, so be it).

I mean, even the most 'complex' apps I mentioned (like Antidote or, say, Affinity Designer) most users should be able to start using them quick (not master them, but start using them) because they're not that complex and not that different. Mmm, I'm not an expert UI designer, it's difficult to explain my feelings around that notion: many things are familiar if not similar between those apps, heck some are even so simple that there is no such thing as a 'save' button. I know it's also very much a question of education and of acquired habits, but still this matters a lot to me and probably to other people like me. I'm getting old (and I'm not in good health) and I want to spend as little as possible of the time I have left learning new apps, to tweak them, or search for workarounds just so I could do what I've known how to do for many decades already. If I was to summarize what I failed to say: I switched to Linux not because I'm interested in learning new apps or in changing my desktop look (it's really cool, I just don't care much). I switched because I worry about the lightning fast erosion of our privacy in this digital world. It's the ideology that attracted me to GNU/Linux. I have no major issues using apps under macOS/iOS, I only have major issues with Apple (and MS, and Google, and Facebook, Twitter, and so many other corporations) acting like assholes willing to destroy our societies and even the world itself so they can make a few dollars more during the next quarter. F. that, that's my motivation to use G/L ;)

Also, thx for reading to that point without burning me (you will find a box of matches in the second drawer over there, you know where to find me) ;)

Windows/Games working out of the box with zero tinkering.
No amoint of proton or other software works as well for me as it seemingly does for others

OS-level support for cloud storage. OneDrive, Dropbox and all the others work seamlessly on Windows through the Windows API. You can browse all the files on the file system and once you access them, the OS will call back the cloud provider to download them. It works through all applications, all cloud providers. I am aware that some tools on Linux have something similar to work around the issue in user land. Some solutions are less worse than others but none of them are as good as on Windows.

I miss windows eating my work when it chooses to install updates and reboot automatically while I'm asleep

Edit: even after I've set registry flags and policies to "never automatically reboot" - it's always fun losing 4 days of work because windows randomly says "fuck you"
