Hello all. trying to write a how to book for my field of labor (Mechanic). Unfortunately can't type worth a flip. Would LOVE!!! to speak into my iphone 4 while going over steps of troubleshooting various problems and have it converted to usable text that i could save / edit. Does anyone have any experience / suggestions / comments on what's available as an app or otherwise do the task as i described? Is this technology even developed enough to use in this way?
