One of the exceptional features of the M20x is the three built-in microphones and how well they work for speech recognition. This works remarkably well. There have been some reports here about people who have tried using the bluetooth wireless headsets without much success. I don't recall anyone having any notable success with any of the Tablet PCs. The issue is either a lack of bluetooth support for the headset device profile, and/or noise levels in the device that exceed the tolerance of the speech recognition.
Check out the M200/M205 FAQ link below. There are several references to the microphones and speech recognition.
