I had missed the laptop comparison in crowdsupply.com.
I guess it is too late to change anything, but anyway, just in case someone thinks the links are relevant:
On planned obsolescence: " The possibility of a manufacturer actually deciding to SHUT DOWN such laptops is not unthinkable. "
Other kind of computers (Revolv home automation) have already been shut down ( I think, all news I have are from one month before the deadline)

Summary: Google (or Alphabet) buys Nest. Nest buys competitor Revolv. They announce they will OTA-brick all of 300$-a-piece Revolv home automation hubs in May 2015. Customers are left to buy something else (if they aren't already fed up).
Curious that you left out GTA04, neo900, Pyra. And the refurbished RYF laptops, which are (software) efforts to recycle old standard laptops with libreboot, and so have some FS and eco conciousness to them (by the way the Acer 201P hints that the Rockchip 3288 SOC might be usable in a future CPU card ? https://libreboot.org/docs/hcl/c201.html if power allows http://www.cnx-software.com/2015/02/17/power-consumption-of-amlogic-s812-and... - not that Rockchip is a good company, from what I hear about GPL violations - anyway fixing the boot with JZ4775 cpu card maybe is more prioritary than designing new CPU cards).
But I learned about a lot of projects I didn't know. Thank you. I also didn't know Tegra laptops were locked down. I though there was The Jetson TK1 board that people used with 100% free software

But then Debian says it needs two blobs (firmware for graphics and USB xHCI, I don't know how usable it is without these)

I hoped some Tegra K1 laptop could be eventually liberated (K1 chromebooks have coreboot, no libreboot yet, and your update hints at they have already been found unliberable because of DRM in the laptops?).
Btw, sorry for the trivia and mixing topics, but are there images available of the different colours offered for the EOMA68 laptop housing ?
