I've been using voice-activated software from time to time, mainly when I'd like a break from long periods of intensive typing. I find voice dictation useful mainly for first drafts, not editing, but it's great to be able to "write" while I'm walking around in my office (my headphone/microphone set has a long cord). I use MacSpeech, which uses dictation technology from Nuance, the company that makes Naturally Speaking, voice dictation software for Windows. When I'm away from my laptop, I've started using Dragon Dictation for the iPhone (which is FREE right now) and I'm really impressed. The text in the screenshot above/left was dictated by me a few minutes ago, with no edits. You can dictate up to 20-30 seconds at a time, with the text accumulating on the iPhone screen. When you're finished, you can e-mail yourself the text or copy/paste it into the iPhone app of your choice. Like any voice-activated software, the transcription isn't always perfect, but it beats the heck out of trying to thumb-type text while you're walking or having to manually transcribe a recorded message later.
