GUEST< DB sez, "Most people who I've heard dismissing it seem to do so because it's not 100% accurate. This seems to me to be a preposterous attitude..."

Not really. I have a friend who is blind, and is understandably frustrated by the inaccuracies in all voice recognition software. 100% accuracy would be ideal (nay, essential!) in her situation. I can't imagine having the patience to "train" such software if you can't proofread what it writes!
