Then again, CES will probably have a lot of new smartwatch announcements, so it might be
worth waiting a few days before making a decision.
Of course, you could always just
wait for Google to start sending these patches out to users with compatible phones as over-the-air software updates, though it is
worth keeping in mind that those updates aren't likely to go out to phones for at least another
day, perhaps a
few, so if you want the latest patch sooner rather than later you'll want to grab the necessary files and manually flash them to your device.
