@bolwerk No, it’s not at all amazing that hardware support is still an issue in Linux, because there are still many vendors which refuse to release Free / open-source drivers, or hardware specifications so that the community can develop our own. Binary-blob drivers will always cause problems in Linux, because the kernel is a heterogenous environment requiring well-known interfaces. Closed-source drivers are an unacceptable security risk for many environments as well- but until recently this hasn’t been an issue for things like video and wireless hardware, two notorious problem areas for Linux drivers (when was the last time you heard of a SATA controller not recognized by the kernel?)
Also, your question is not about hardware but about support for that hardware, which could mean either compatibility with Linux (a reasonable interpretation given your phrasing, which @jerv and @Lightlyseared addressed) or technical support from the vendor (which you can get from System76 or from Canonical if you use Ubuntu.) There’s no need to get snarky with people trying to answer your question, especially when you could answer it yourself with a few minutes’ googling.
And yes, the Wasp is a $4100 laptop and weighs a bit more than other devices- on the other hand, it can survive being run over by a car. Milspec ruggedized costs more. It wasn’t meant as a product recommendation, only a suggestion that you could perhaps find some vendors and search their sites to find something.
Or you could just get one of these…
Oh yeah, I forgot to mention tuxmobil.org also.
