As promised during the Google(s goog) I/O keynote, the first two devices running Android Wear have gone on sale in the United States. If you head on over to Google Play's devices section, you can choose between buy a LG G Watch for $229, or a Samsung Gear Live for $199. Both devices will ship in early July. We're not sure which one is the one to choose at the moment, but tomorrow, as part of our comprehensive Google I/O coverage, we'll have a hands-on with both devices, if you can wait that long.
