Google also recently sent us another Android Wear watch we hadn't seen before—LG's G Watch R, the round version of the regular square G Watch we looked at back when Android Wear launched. It looks more like a finished product today, where as the first G Watch looked like no-frills development hardware. The G Watch R also doesn't use the old power-hungry internals that give the Moto 360 so many problems.
So armed with a new watch and new software, we spent a full month wearing Android Wear to get a sense of how far it's come since its original release a little over six months ago. While not all of our initial complaints have been addressed, not by a long shot, there are definitely signs of progress.
Android Wear 5.0, specifically
