google really needs to enable these devices with specific identification codes tied to an account to keep them from being stolen and re-sold. otherwise, it's useless for most purposes.
for example, if someone steals the device, all they have to do is wipe it themselves, which takes seconds. even if they don't wipe it, all they have to do is disable wifi or disable GPS. even if the thief disables GPS but uses their own wifi service, the device will be unable to be tracked, not even an IP address is recorded. I don't often lose devices in my own home. I'm more worried about theft than losing a device at home. It'd be nice to have the piece of mind that if my device was ever stolen, no matter who they sold it to, it would list me as the owner and notify me whenever and wherever it's used in the future so that I can take appropriate action in either reclaiming it from the person it was sold to or prosecuting the thief. The irony of it all, is such a feature would be EASY to implement yet it does not exist.
Even wiping your device remotely is both pointless and detrimental. If a person really wanted your data, a wipe wouldn't get rid of it. Running a deleted file recover would reveal everything that was 'wiped'. Then the detrimental part is wiping the device removes the ability to track it anymore...it's essentially unrecoverable after that. So you have to choose between having your account compromised with the hopes that the thief is stupid enough to 1) leave the device on 2) leave GPS on 3) connect to the internet through wifi 4) not wipe the device themselves.....or losing your device for good. when you break it down, there isn't any protection for your data at all no matter what steps you take, unless you encrypt the entire OS....but even then a wipe will factory reset and that won't detour theft.
