Mark was not liked by all at Teradata nor NCR either, at times I complained, but really looking at the big picture, there was nothing else that would have worked. When iconoclast make unpopular decisions the masses don't like it. The vision and dedication, plus simplification of complex ideas, this is so attractive, there are not that many of those around globally with the chuzpah and pioneer spirit that is what needs to be celebrated and admired. Every man has fault and makes mistakes, who is free of that, if anyone is please I want to hear from you in a New York minute. RIP Mark
