I don't know, Trident, this is pretty flawless.
That said, you're right - you have to experiment a little. For example, in the kitchen, if I select the most recent Kaiser MSVC build, my jawbone fails to initiate voice command. But if I choose Luv2chills, it works fine. So there's a bit of trial and error, but I've been using it for about 2 hours today and I'm blown away.
