I went through a two-year period where I didn't have a decent job and couldn't afford a computer of any kind for myself. I ended up spending some time volunteering for a local non-profit, and they gave me an "old laptop" they had in storage. This was in ~2005.
It was a Sony Vaio, and the only thing I really remember about the hardware/specs is that it had a physical scroll widget under the touchpad on the edge of the case. Software-wise, it was running some relatively locked down version of Windows. I installed Arch on it and used it to rebuild and manage the non-profit's website.
The other thing that I remember from it is that it was my entrance into using the terminal as my primary interface - the first place I used Vim regularly, and the first time I'd installed tmux. One day I was trying to test a dropdown or something on their website, and discovered that my touchpad didn't work. It turned out to have been broken by an Arch update, which wasn't terribly surprising. What was surprising is that once I'd traced down the issue and corrected it, I realized that it had been broken for almost two weeks. I'd used that computer every day and hadn't needed to use a mouse even once.
