Yeah, ZooT, but if I wanted a portable OS, I'd tend to prefer something a little heftier, like a live CD distro of Linux. DamnSmall Linux fits on a 50 meg business card CD, runs from it, and has a GUI. It does use a graphical (<-- heheh, that should say "text-based") client for AOL Instant Messenger (nAIM) and the PPP client is mostly text based to save space.
