Brian-
That's the mic that I use at work! Works really well...
The ability to dictate in a mobile fashion can be important. That's the one drawback of my prior solutions- from the Windows CE-based Airpanels (no dictation software could be loaded) to the HP TC-1000 tablet (had a limit of 750MB ram from which the display drew its share of memory) which just didn't allow for dictation.
I currently dictate to my desktop, which isn't bad, as it allows me to separate from the patient then hand off the chart to my nurse. The 3.4 GHz CPU with 3GB RAM makes dictation a breeze.
BTW- found a cheap DNS9 Preferred "Buy It Now" ($76 incl S&H):
