Although my total experience with Linux (including the time I've spent with the toolserver) is much less than 100 hours, and I spent at least an hour in Windows environment every day, I found Linux environment easy to learn, at least for the purpose of working with Toolserver. Personally, I have never encountered a situation with the Toolserver which needed it to be running on a Windows operating system. So in my views, Linux is fine and enough.
