Well, I have looked at the links, thanks, and Googled a bit more, and I am really where I was a couple of years back when I dallied with Linux.
It is going into the 'too difficult' box (again) I'm afraid, as I have to print off my Googling (in Windows) then reboot in Knoppix, find it is not quite working, go back into Windows etc etc and it is just all too difficult. An OS for 'erks' needs to be intuitive and is not, and much as I dislike the MS world, it is more-so, with plug-and-play etc.
