Must confess that 10 years ago I lost around 5 years in deep linux setup & programming, and I know all that you say. Neither [1] nor [2] do not list recent specific hardware models, I mean, notebooks and PCs, not chips or boards. Regular user has to unpack the device and `lspci -vnn -d 14e4:` (amazingly clear for regular user?), or something in live-usb system console at the store under manager's sight to maybe estimate whether this wifi is able to work with specific distro, which alone is a big question until you try it. Repeat these steps for all the hardware in
potential purchase, and good luck to find all the specs, because often it is just i5/16Gb/13". There also are unresearchable timebombs like fast battery discharge and sleep issues under non-supported OSes.
"Product" is at least a site like easylinux.com, where you see that in late 2016 you can buy compatible X,Y and almost compatible Z (bios-only fan control), and in 2015 there were A,B,C, and in 2014 D was the best choice. Please click on direct link, torrent or ftp to download a distro image that already contains all the specific drivers and software.
Obviously, I'm unable to provide any evidence for something that doesn't exist.
