I have been using Linux Ubuntu 10.10 for a while now. I am really getting to like it more and more. I would like some of the more of the ham software work on linux, of course maybe I need to learn some more about the OS. I have been reading and working with the command line and this has been a fun learning experience. I found a nice article about when is it time to switch to Linux, so I have linked it here. Take a look at the article it has some good points.
