The thing that you're missing here is that the mainframes are the fundamentals. I'm currently a 26 year old mainframe programmer/analyst and I have 6 months left to complete my CS degree. The fundamentals that I have learned on the mainframe have completely dumbed down just about everything on the other systems. After OJT learning languages like COBOL, languages like VB.NET are significantly easier for me to learn and understand. This is the same thing for OS support. Yes I may need to look up the syntaxes but if you know where to find the information a 10 year old could support Windows. Learning Windows is in no way shape or form learning the fundamentals.
