i know running a beta is subject to potential problems and i usually shy away, but i was advised by Garmin that they fixed the Notifications widget bugs in the beta and i was urged to try it out. (the bugs are: double tap/click often required to view a message and also, widget locking up watch (happened twice with my first watch but hasn't happened on my second watch)
i know one person had issues with false low battery warnings. anything else to be concerned about in joining the bleeding edge...
