David,
I'm curious as to what microphone you are using to get that 99% accuracy. I'm a fan of my Revo xTag, because of mobility and convenience, but it's nowhere near that accuracy. Even so, I can't imagine not using Dragon with AC. It is simply the fastest way to go. Unfortunately, my 3 year old xTag battery is starting to falter, so it's either time to send it off for a new battery, get another xTag (probably what I'll do), or look for something new like the Phillips Speechmike Air.
