True, but running a LiveCD as a primary OS is just asking for trouble, IMO. Better to use it as an option for recovering a computer that's been completely screwed over by junkware, IMO.
Why do you say that? I use a Knoppix liveCD all the time. I put my information, bookmarks and other stuff on a USB key, boot and run. When I am done banking I shutdown and remove the usb key.
