I think I need to narrow some things down;

My current Windows PC isn’t what I’m looking for; it’s a big and powerful gaming laptop from a few years back. I’m looking for something light and portable, but with a full keyboard for coding.

Pricewise I’m looking for something around $350; if this is unreasonable let me know.

As I understand it, Steam Deck uses KDE, so I’d like to stick with that for now.

This is probably the most helpful advice I think I’ve gotten so far. Thank you, I’ll look into these options.

I should add that I’ve been interested in getting a small, portable notebook for coding separate of this, and making it Linux seemed a good idea at the same time.

They could hold up a flat planet.

Does anybody have a Cats are Liquid community here?
