Recently, the Android Wear operating system got an update that was somewhat overdue in coming.
One of the first things of note was the fact that there is no longer a card covering the main watch face. It was ok having a card covering half of the face at times; however, it really detracted from the idea of having a watch. Now, instead of having a card always peeking up, you just have to swipe up to bring the first card up.
Second, Google Play music is now available on the watch. With a pair of Bluetooth headphones, you can listen to music straight from your watch.
Third, when streaming music, there always was a card that showed you what was playing, and if you kept swiping, to the left you would find other controls. Now, a swipe to the left brings up four different buttons: one to skip forward, one to skip backwards, and two to adjust the volume.
All in all, this was an update that really increases the usability of Android Wear supported devices.
