When I was shopping Lenovo.com for my ThinkPad in 2018, there was a table with ThinkPads certified for Ubuntu Linux in one column, and certified for Red Hat Enterprise Linux in another column.

I chose the T580 as a RHEL-certified notebook, and it was fantastic. Lenovo.com let me configure each individual component exactly according to my needs and tastes, and it was custom-assembled and shipped from Shenzhen.

It did arrive with Windows 10 pre-installed (this was the least hassle and most popular OS option). I initially installed CentOS, but quickly realized that Fedora would be the sweet spot, and so it was a Fedora system for most of its lifetime. Near the end, I did revert to Windows 10, which also worked flawlessly.

The ThinkPad T580 literally never malfunctioned. It was still 100% working when I turned it in for recycling in 2025.

I've also run Ubuntu on my "daily driver" desktop system, which ran from 2006-2022. Yes, that's 16 years' worth of Ubuntu installs and upgrades. It was mostly a KDE Plasma (Kubuntu) system. I enjoyed every bit of that.

In 1999, I was avidly using OpenBSD on really old hardware (such as HP Apollo 425t workstations.) OpenBSD simply couldn't deal with the special graphics subsystem on those machines. I tried and tried to get something working, but there were obstacles, not only with the hardware and drivers, but also the monitor connection needed a particular type of cabling and a proprietary monitor, too.

However, OpenBSD did great for networking, security, Squid cache, proxies, all kinds of things. And even in 1999, though it was early, I ran Linux on a 386DX-40, because Linux supported the "ftape" floppy tape driver at that time, and I had some kind of QIC tape backup from Eagle that wouldn't be recognized by OpenBSD or NetBSD.

Meanwhile, in that same year, my "daily driver" desktop machine was a 486 with VLB, dual-booting Windows 98 and OpenBSD. The Windows 98 was set up with a Cygwin system and X11 server, so that I could run X11 clients on the OpenBSD machines, or the Linux machine, or whatever else was on the LAN.
