Well, I went ahead and tried it. The music sounds incredible through the Widcomm stack- holy cow does it make an improvement. However, I lost most of the actual headset functionality like being able to activate VC by holding the one button on the headset. Also, I can't even get the headset to answer calls. Thus, for now, I'm going back to MS. However, I cannot wait for them to get this thing ironed out- the interface is twenty times better and will be an invaluable add on, when it's ready.
