Technoethical team is happy to announce the T400s (not to be confused with
his older brother T400):
https://technoethical.com/laptops/tet-t400s
This is the ideal laptop for those who waver between the X200 and T400: it is
much lighter and slimmer than T400 but as powerful, and it has a touchpad, a
wider screen and an optical unit, when compared to the smaller X200. The
T400s is the most modern x86_64 laptop supported by Libreboot! It is also
very rare and the hardest to flash externally with Libreboot, harder than the
X200 Tablet.
Like all Technoethical laptops, the T400s comes preinstalled with fully free
distributions of GNU, and by default with Trisquel:
