That's the only way I try out distros, even if I've installed and regularly use a previous version of it. Of course, for all I know, both the Intrepid and now Jaunty LiveCDs could have this wireless issue while a full install wouldn't--I might not ever know, as I don't have the time nor the inclination right now to install them if I don't have an indication from the LiveCDs that they'll work properly. But I'll probably end up waiting it out until the next LTS before any switches happen, whether it's to the LTS or another distro.
