Geniunely curious, what are these annoyances? I only started using Linux (Ubuntu) around 2013 so I might miss most of these issues. Tho I'm still dual-booting Windows cuz of an old game with anti-cheat that refuses to run on Wine.
Yes, I'm a "noob" but like I said I have been doing this for 20 years. Have been a fulltime CTO for most of those years. Do server side linux admin fairly regularly as well.
And even despite all that and more I am so happy to be rid of windows as a daily driver.
For me, it is lack of business critical applications. For example I use Microsoft Teams to attend meetings multiples times a day. And there is no Teams client for Linux.
Here's one: Why does the OneDrive option load 3-4 seconds AFTER the new right click context menu loads causing everything to move down and for me to click the wrong thing as it moves under my mouse cursor? I hated that on the web so they brought it to the desktop UI.
