Ask HN: What do you put on a new computer?

I'm getting a new computer for the first time in ~6 years. I've been on MBP/OSX for the last 8 years, and before that was running dual boot Ubuntu/Windows for 7 years.

I'm switching back to a Thinkpad, and I'd like to see what you all do with a new computer? Do you wipe it? Use VMs? What flavor of OS?

If it's any help, my full-time job is doing Ruby on Rails / React / Flutter. I also play around with Aseprite (pixel art) + Krita (using a Wacom) and game dev with Godot. And (very rare) gaming, though I would like to play more...

Thanks for your recommendations.
