I'm looking at the feature matrix, still trying to decide.

Can anyone review these features?

1. Create custom "Text-and-Graphics Commands" to automatically insert unlimited boilerplate text and graphics

2. Audio Playback of what you dictated in the open document.

3. Allows transcription from digital recorders, Pocket PC, PalmOne Tungsten

4. Text-To-Speech in editable text: a synthesized voice reads out text you designated.

What is the difference, if any between 2 and 4?
