Ask HN: What are the first things you do with a new laptop?

As title, I recently got a new laptop I'd like to keep exclusively for studying and personal stuff, while anything job-related is on a different machine.

What are some must-have applications you install immediately ?

Have you got some settings you absolutely need ?

Do you set it up to match your workflow or do you experiment something new given the chance to start from scratch ?

I'm on Linux, precisely Pop Os, if it matters.
