"IMHO Java's success today is more because of corporate inertia than anything else."

I don't think so. Java as a platform is a lot easier to manage than most other platforms, including Ruby and Python. Jars, in my experience, are much easier to deal with than Gems. Java has a set of advantages that aren't really replicated elsewhere. It's garbage collected and portable, but executes much faster than other garbage collected and portable languages.
