Libreboot laptop prices temporarily reduced, on https://minifree.org/ - a price reduction of £20. This discount will last until about ~16th of February.
These are secure machines that come with Libreboot pre-installed, which replaces proprietary BIOS/UEFI firmware. Libreboot offers greater security and fast boot speeds compared to most proprietary firmware. I lead the Libreboot project; sales fund the project.
Your choice of Debian Linux, other distro or a BSD system e.g. OpenBSD/FreeBSD.
