I've not done antix but MX on the laptop you helped me find don't seem too bad. I am looking at finding something for the box I still have though. As old as she is I'll probably be looking for a lightweight 64bit on her. Was checking out the lightweight distros lists and noticed that a couple included Debian Mate for some reason as a lightweight for older machines. I've looked at LXLE, LXDE(not crazy about) Liinux Lite. Have also looked at Pup. Even was reading the arguments of for and against running a distro in root all the time such as that one link I posted for Nubi about Fatdog.
This box is that old MS Windows XP Media Center Edition 2005. Still going. Figure will use until it gives up it's ghost. But now wanting to look at the lightweights since it's this old, what about 13 or 14 years old now? Have been running Debian on it since I installed Squeeze that time.
