For gaming, I have a dedicated device - a Nintendo Switch, but I also play indie PC games like Slay the Spire, Forge MTG, some puzzle games e.g. TIS-100.
Linux with i3 is fast and responsive. I write code in the terminal, no fancy debuggers, no million plugins, no Electron mess.
It’s enough for everything I need, and I don’t see a reason to ever upgrade. Unless my hardware starts failing, of course.
