It's still surprising to me that in 2008, Linux is still really new to a lot of people. When you've been working with Linux for over 10 years, you tend to forget that there are still people who have only heard about it. Maybe they were given a really old CD of a release from many many years ago and they "have been meaning to try it out." The LiveUSB method with Fedora makes that a little more accessible. In Fedora world, it's impossible to wait to try a release. You can't get an installable CD and shelve it for a year and then try it out. By then, we've made two more releases. It just moves so fast. So we need a fast way for people to try it out. The LiveUSB method is great for that.
