Just noticed that my #Thinkpad #X240 / #X250 #Debian Sid (aka #DebianUnstable) installation had its 10th anniversary in April this year via https://packages.debian.org/unstable/installation-birthday
The installation is older than the X250 as I initially bought an X240: It finally had a usable resolution compared to the X230—but the awkward touchpad without hardware buttons for the thumbstick. So the next year I bought an X250 and moved over the installation. And my father got an X240 for his birthday. 😇
