Hot topic I see
UPDATE
Man this is awesome! The Freedom keychain GPS paired up no problem and both Google Maps and MS Live Search or whatever work great with it.
I'll give it a better run tomorrow while I drive to work and see how well it keeps up.
VERY satisfied so far.
I went so far as to remap my Home key to open Live Search instead of the Quick App application.
GPS seems to work in my pocket in the middle of my house... pretty amazing compared to earlier technology that needed a clear unobstructed view of the sky to function.
If all goes well I may go as far as to sell my Garmin Nuvi 360 and just use this from now on.
