Yeah. Using VMware, I load them up frequently to see if I like them or not. So far, I still always come back to FC. I'm thinking it's because that's what I'm most familiar with.
I have a DVD image that I still need to burn that contains 10 live CD distros. Most of them are specialized for forensics, and a couple are GP distros for demos. It's pretty cool, but it's taking up 4G of my /home partition. :(
Same here. I liked Kubuntu, but I need my wife to test drive it before I change our laptops over. FC5 has some weirdnesses that have kept me from going to it on the laptops, which are still on FC4. At work, I have to connect to one of those evil 'exchange' servers, and FC5 broke on that completely. Evolution locks up every time I try to pull mail. Spent over an hour today off and on beating up my installation to get it to cooperate because I'm sick to death of webmail, to no avail. I may have to drop back to FC4 on this box, which sucks because I like the wireless tools on FC5 better.
