I have a laptop from the 90s that still works. So a laptop that does not die is, in itself, not that big of a deal. The main reason why I pretty much exclusively buy old business Thinkpads is that they are incredibly serviceable, and you can get replacement parts for many years (and also very cheap if the laptop is older). Also, there's a big community for running Linux on Thinkpads, so the hardware is usually very well supported, including kernel modules for fan control and stuff like that. However, it's not all sunshine. Especially during the T4xx era, many business Thinkpads had absolutely terrible displays by default (can usually be replaced with a proper one, but adds additional cost). The T440 had a horrible trackpad where they ditched the dedicated buttons (again, can usually be replaced it with a proper one). So do some research before buying. Also, before buying from a commercial refurbisher, check if there's a Thinkpad community forum or similar in your area of the world, you'll often find stuff much cheaper there.
