Indeed! It depends what you’re doing on it. Because there’s a wealth of computer activities that have not increased in actual power demand in decades. Sure they keep making software more bloated to keep the need up, but if you throw an efficient distro on a machine and only need it for basic office type things like office suites, email etc. and even basic graphics editing, you can use a 25 year old machine and do just fine. It will run, and it will do the job well, and you’re never going to feel like it’s slow. Maybe not as glitzy as newer ones, but that is where you’re already beyond need and into want.

The only things that are tricky are internet connections with anything using web protocols, due to certificate tech etc. and that can be handled by using a still-maintained browser such as a Firefox fork, and email can be done via software like Thunderbird, which doesn’t have to render the bloated front-ends of many email providers.
