If you don’t need a laptop, I’ve been having a blast with using mini/micro/tiny business PCs off of eBay. I’ve had zero issues installing Debian on them, and they’re designed to be easy to maintain by IT departments, so Wi-Fi, storage, RAM, and even CPUs are all replaceable. They are mobile CPUs, so if you need the heavy lifting of desktop CPUs, you’d probably need to go with a larger form factor.
The joke in my friend group was that Waterworld was Dances with Wolves on water. The Postman was Waterworld on land. Dances with Wolves was the Postman with Native Americans. Toss in whichever parallel you feel works best to not actually say the movie you’re putting on.
