I just got this up and running on Tuesday and I'm surprised how accurate it is. I had an old version of dragon naturally speaking on my old computer but it made so many errors it was hard to use and on top of that it made my computer freeze a lot. This doesn't seem to make many errors and runs nicely on my computer. Just thought I'd mention it in case anyone has Windows Vista wants to give it a try. It's pretty easy to setup, you just need a microphone. The hardest part is learning all the commands. I can't type at all so it sure beats the old "hunt and peck" when you're in pain.
