I think you're probably trying to say something important, but this post doesn't express it very well. Maybe try again, and start by imaging yourself explaining it clearly to someone who has never encountered the idea before. (Also, think about whether it really belongs in the Ask community, or might be a better discussion for a different group.)
Yeah, this. In fact, going with hardware that's too-too new can lead to a different problem on Linux.
OP, if you're buying hardware, it's worth web searching to make sure people have tried it on Linux and are having good experiences with it. Since most manufacturers only care if their stuff works on Windows, it can take a little while for Linux devs to write drivers and get them shipped in Linux distros.
No, that's PCP. You're thinking of the financial payment processing compliance regulation.
