"but python + any python IDE < Java + IntelliJ IDEA(Eclipse/NetBeans)" (and I suppose s/python/ruby/g and s/Java/C#/g too) I don't quite agree with this statement as I find python and ruby development easy, perfectly usable and well performing in a generic code editor (vim, emacs, textmate) whereas doing Java or C# almost mandates a full-blown heavyweight IDE with smart code completion like IntelliSense to get anywhere near the same efficiency. I've tried a few IDEs for python and ruby, and they seemed almost more of a hindrance than a help, and definitely not a significant improvement.
