Pretty much the same trajectory. I started at my T420 around 2010 and that time I just main laptop, computer. Then, as I have a more powerful desktop, this T420 becomes my secondary computer and I started to experience Linux with it. After almost 15 years I end up converted it into a PVE host and run just one or two virtual machines on it and it's quite durable I can still do functional work on it, quite remarkable how a computer can last so long.
