To be fair. All good distros can run from a USB stick or whatever now. The use case for a "liveCD" is limited. Puppy Linux would just be a toy today. It used to matter to me in the days of slow internet, limited storage, etc.
Now just grab Linux Mint or whatever. Use a "real" distro with a community. Install it if you like it.
