> an old laptop that can run a modern browser. This requirement means that it mustn't be a very old laptop. I have a nice IBM R52 Thinkpad, Pentium M 1.8 GHz, 512 MB memory that runs Antix Linux but struggles to run a modern web browser. It seems to me that if you can run a modern web browser then you have enough hardware to run a modern OS locally.
