Among the things I did not like in the older version is that it was rather difficult to get information *out* of Sticky Brain into other application. Notebook exports to PDF, HTML, and other formats rather easily. Also Notebook, organized as a collection of individual volumes, seemed neater and more organized. On the plus side, I liked the simplicity of storing web pages and web receipts in a permanent form.
At the moment, there are three big organizer products for Mac OS X, including Omni Outliner. Choosing between them can be difficult. I probably spend over half of my computing time with a organizer application and want it to be the best experience it can be.
