As a Windows junky, i usually ignore these Linux releases -after all, there are so many. However, after installing Redhat 9 recently(the basis for Fedora), i completely changed my view on Linux. If you want something simple to use, simple to try, try Fedora, or Redhat 9. I was bowled over by how simple it was to setup and get on the web, with all my favorite open source programs (firefox, thunderbird etc) there.
