Sadly this sounds exactly like many of the PC based programmers across the hall. What is it with them? Its like water cooler hell with some of them, and share code - hell they all can implement X better than someone else. Is there just so much language bravado amongst this class of programmers or did it bleed through from school? I have listened in arguments between Java programmers, C#, and the like, and never understood the animosity some have.
