I purchased Xmind in an earlier version and found it clunky and unstable. I also own Novamind Pro and Curio. I recently took another look at the software using the latest version. WOW!!! It's incredibly useful, stable and fast. I like it much more than NovaMind in terms of it's range of functions. It's the mindmapping program that I've been wanting and fills voids that Novamind has not.

Hat's off to Xmind.
