Jon,
I've been using the SpeechWare 3in1 table mike since it's release in February. My old 2in1 was a tremendous improvement over my Revo xTag lapel mike, but the 3in1 is even better. You can dictate from a greater distance and with more background noise. I dictate notes at my office desk between each patient using narrative, Dragon templates, AC templates and mouse clicks. I have a kazoo hung from my neck and cymbals between my knees. Overall, I have gotten quite speedy, but I digress...
Yes, buy the 3in1, you won't be sorry. 6in1 just has more features you will never use.
Dave
