I was more thinking along the lines of most people know Windows, and probably Mac, and some have heard of Linux,
But I was looking at all the various different live OSs (although most of them are just different flavours of Linux) and thinking "so many options...but I don't know anyone else who would know anything about any of them and they would all look at me like.."huh?"'"
Who wants to start a thread on all the OSs they have used/tried out and a brief opinion.
Saw something about Plan 9 somewhere, which looked cute enough to try out
Only, I haven't the time or spare computer. But, again.... how many people have even heard of it??
