I got interested in free software by reading the <a href="https://www.gnu.org/gnu/thegnuproject.html">about GNU</a> page in the GNU Emacs editor. Free software back then and certainly now is quite usable, typically without much closed-source software. One area where free software is lacking is firmware and this led me to want to try libreboot on that ThinkPad x60. A few years forward and I became a coreboot contributor and eventually got a job at 9elements because of this. In that journey I amassed quite a hefty ThinkPad collection. I wanted something that was speedier and 64-bit so I got a ThinkPad x200 which I ran for a few years. I got a ThinkPad x220 a few years later, as the Sandy Bridge chip is substantially faster than the Core 2 Duo inside the x200. To port or improve existing coreboot ports I received a ThinkPad x201 and R500. A few years back someone figured out a way to get past Boot Guard (<a href="https://github.com/coreboot/deguard">deguard</a> ) on Intel Skylake/Kabylake, so I got myself a ThinkPad t480 and I&#39;m very happy with it.</p>
