I have used Nuance's Dragon NaturallySpeaking 12 on my laptop for a few years. Now that I got a SP3 I bought version 13 and it works fantastically well on that device. So far, limited to one day, I have actually achieved almost 100% accuracy, it even correctly recognized boarder instead of the more common border. Now I just wish I could use my phone for input instead of a headset, looks kind of arrogant in a Starbucks.
