The black leather Moto 360 is currently up on the U.S. Play Store, though it probably won't last long. After going out of stock pretty much immediately at launch several days ago, it is already listed as shipping September 22nd, a full two weeks from now. The gray leather variant remains out of stock.
Update #1 9/8/14 1:55pm PT: Aaaand it's gone.
Update #2 9/9/14 1:15pm PT: Back in stock. This time, it "leaves warehouse in 2 - 3 weeks."
Update #3 9/9/14 3:37pm PT: Sold out again.
The Moto 360 has been in high demand, though some early reviews indicate poor performance and battery life, especially with the ambient display setting turned on (we're talking having trouble getting through a single day without recharging). Performance problems could be attributed to the use of the ancient OMAP 3 processor, while battery life issues stem from a combination of a smaller compared to other Android Wear watches 320mAh battery, a relatively large backlit LCD, non-optimized software, and, well, that ancient power-hungry processor again.
If you're still lusting after the Moto 360 and for some reason detest Best Buy, which should have it in stock at most locations on September 14th, here's your chance to claim it through the Play Store. Hurry, because it probably won't last long.
Thanks, Corey Watford and Tom.
