Early into high school, I needed something to take to class, but since I already had a decent desktop at home, plus we were broke, I picked up some cheap Asus K55N; AMD A8-4500M, 4GB DDR3, etc -- nothing particularly fancy; only upgrade I did to it was removing the mechanical hard drive and swapping in my old 120GB Corsair Force GT.
I eventually upgraded, went off to university, etc. When I finally came home, I found out my mom apparently "borrowed" it, figured out how to install Ubuntu, and has been using it ever since for grading papers and what not.
No idea how much longer it will remain in use, but aside from the awful screen, ironically, honestly, I think the browser and the seemingly ever increasing resource requirements of the web will eventually be the only thing that finally causes an upgrade.
I've got a desktop with a Core2Quad Q9300, originally built in 2008. Updated the motherboard in 2010 to one with USB3, updated the GPU in 2012. Kept using that machine as my daily-driver until 2020, when I built my current desktop. The only real reason that I did that was to improve gaming performance. The machine itself still functions fine on the modern web (using an up-to-date Linux distro, of course). 8GB of RAM used to feel like a monster.
