I have the Fedora 12 and OpenSuSE 11.2 DVDs here and I just haven't got around to trying them yet. I also have Ubuntu and Kubuntu 9.04/9.10 Live CDs but I've only tried 9.04. I struggle to find a reason for using Linux as opposed to Windows, since most of the OSS that I use has a Windows version anyway. I suppose the whole philosophy thing doesn't really click with me. I use a PC to get things done, not fit an ideology. Whatever can do the task I'll use.
