Thank you Owafo for your detailed response.
I ended up buying four Spin 7 yesterday on sale at Costco for just $899 each. I had read the first link, and I just sent an email to Insyde vigorously complaining about their lack of LInux support, even though they state that their BIOS allows you to "Deploy platforms with multiple OSes", and that they have Linux "experts" on their team.
I used to love Windows 2000 and XP, was ok with Windows 7, but cannot stand Windows 8 or even 10 due to the increased MS spyware regardless of how much you disable or even try to filter MS chatty traffic at the firewall level.
Thanks to Costco's generous 90-day return policy, I'll keep them for a while trying to get some LInux distro working, whether in single or dual boot with Windows 10, since there aren't any more Windows 7 drivers for these new machines (which I can understand from the manufacturer's perspective).
I'll share back with the community if I get anything working on the Spin 7.
Enjoy the Holidays !
