ThinkPads are, ostensibly, my introduction to computing. I started really using computers with a ThinkPad T42p, which I no longer own. That really jumpstarted my interest in computing and, to this day, when looking for a PC to take care of a task, I oftentimes look first to a ThinkPad to do the job.

Mugi is the computer that's been in my collection the longest, being my daily driver machine from 2011 all the way to 2018, when I switched to a MacBook (Akari). I was given the opportunity to re-acquire a T42p, on which I installed Windows 7 like the one I had originally ran.
