All of my devices are present, including my S3, S1, Nexus 7, and even my MK808B android TV stick showed up, and declared that it was in my living room (which is correct). Pretty cool. One disadvantage is that it looks like if your device is on wifi where push notifications are blocked (a lot of corp intranets do this) you wont have any luck with using the service. You need to be on truly open wifi, or on 3G/4G to use it. I am going to keep Lookout installed on my devices for a little while, until I am comfortable with this new feature.
