I'm surprised not to see a link to the Librem laptops: https://www.crowdsupply.com/purism/librem-13. They're an attempt to solve the problem being posited, AFAICT, though they ship with Linux, not Windows.
I gave $10 to their initial Kickstarter but have never used one.
Purism/Librem looks extremely similar to System76 - they are rebranded laptops from an Asian ODM running a variant of Linux.
None of their marketing materials make reference to better build quality, battery life, or support, just "security, privacy, and freedom". I would love for them to hit all of these boxes, but I am unsure that their hardware will be as free/secure as they claim (see https://blogs.coreboot.org/blog/2015/02/23/the-truth-about-p...).
Looking forward to the next Linux Action Show which will have a review of the 15" Librem. Meanwhile Chris talks about the Librem on Linux Unplugged, haven't listened to that one yet.
