Ever since Steam released in Beta for Linux (proud owner of the Tux accessory for the Demoman in TF2!) I switched to Linux and stayed there. In the beginning I ran Ubuntu 12.04 and used Steam there. I also used Wine to run Diablo 3 and WoW, although performance was bad at that time. All other programs I needed where there also. (Im a software engineer, so using Linux is even better). But Ubuntu moved to slowly and broke here and there.

What followed was a odyssey between a lot of distributions. Six years ago I tried Void Linux (rolling release without SystemD) and finally settled. Then Steam Proton came around and changed the whole Gaming On Linux scene again for the better. Playing retail WoW with on par performance is now possible. Running any game from Steam on Linux is now a breeze, even if not a native game. Open Source office tools are also on par with Windows / Microsoft counterparts. There really is nothing holding me back from using Linux full time. There is nothing I am missing, and the more I read about problems in the Windows world, the more I am glad I switched all these years ago.

Convincing all my friends doing the same is difficult though. They frankly do not care about privacy or freedom to make the switch. But in the end it is their fault, not mine. If someone comes to me for guidance to make the switch, I will guide them. But I won't evangelise anymore.

There's no equivalent to Excel if you need compatability with a proper Excel spreadsheet (anything more than basic formulae), outside of spinning up a VM.
