This is the first note/reminder tool that I've actually used for more than a few days. You talk, a few minutes later your words are transcribed and appear in a list/folder of your choice. Can be used without the iphone app by calling a tollfree # and following the prompts, but it's the iphone app that makes this truly usable. Could benefit from some minor UI tweaking (took me a few tries to figure out how to direct a dictated note to a specific category), but otherwise it's been flawless for me.

If you find yourself scribbling or forgetting notes, todo items, reminders, random ideas, etc. give it a try. I have no idea how they do this for free. Accuracy is much too good for speech recognition, so there must be a small army of people transcribing.
