"Used to be a fan, no longer use it."
Links. Quirky charm, nice mindmap-style view and other views of notes, programmable links, friendly web-forum and email support. External files can be linked to notes within tinderbox file. Mac only.
Support is needed. Expensive. No longer any embedded images. No embedded anything. Few ready-made templates/examples to allow beginners to get started doing something useful. Frustratingly steep learning curve. Did I mention expensive ?
Potentially very powerful. But then so is C++. OK for enthusiasts but I'm not one. Buy it if you want a new hobby.
