I wouldn't say the other software are more capable, but rather more featureful. The problem with OpenBravo and SugarCRM is that it's really really difficult to use. Every procedure depends on another procedure and you need a Book to get going. As a company that is a massive backshot when you have to teach existing employees. I argue that simplicity in the UI and clear workflows going through the entire application are essential for success, well and marketing. And tree.io had no good marketing, I hope it gets some fresh wind thanks to HN on Github.
