FogBugz has an intelligent design that makes it easy to get issues and customer interaction into the tracker so that it gets in and stays there rather than being scrawled on sticky notes and gone over verbally between only two people in someone's office. It has a good spam filter that does n-category email classification like JGC's POPFile. It has data entry interfaces that combine the best of an unorganized PIM like 37Signals' Backpack with an organized issue tracker like Trac. (Personal experience: Backpack is great to start out with for just about anything, but does not scale over time.) But, these are more about good design than turbogenius brilliance, and good design does not require rocket science, it requires perspective and taste.
