Today I installed TinyXP on a PC with a Pentium II, 350 Mhz, 64MB RAM. Runs like a charm. Quick to start and shut down and it's XP SP3. With a few tweaks everything works and no need to learn a new language (Linux). All you have to do is to keep it hush hush. Version 9 out now. A no-brainer for me (which I need!)
