Cool, I checked as well. The one I had left on charger overnight was updated, so turned on the one that was completely powered down, and when it powered on it immediately looks for any update and within five minutes it was updated as well.
I usually have kept mine in powered down mode, but have decided to keep nearest one in charger disk since it is quicker to use right away. Now, with the tapless mode, it is even easier. Note that pressing main power button once on back puts unit in standby mode, and hands free instructions suggest that be done to save power. Pressing mic button pops unit out of standby, Tapless mode is retained even after complete power down. (To completely power down for no battery drain, hold power button in for 3 seconds until beeps.)
Yes, nice new feature.
