Yes, I agree that Linux has many advantages, not least of which is that the source code is available to all the experts!
I do use a KVM in my development office, so I can swap around my PCs easily. I also have 3 Linux internet servers at an ISP, as we develop web apps using JSP/Java, Oracle etc.
We're using the latest versions on Apache and Tomcat, and I've just received a new test server, on which I'm going to try out JBoss. Also MySQL, as Oracle is too expensive for most of the apps I do. Besides, it's also open source - of which I've become a big fan over the last 2 years!
Again, thanks for your help!
