I recently saw a comment about interference between Bluetooth and Wifi with Android Wear devices. That triggered a thought about the wearability of Android wear on commercial flights. Electronics, such as tablets, phones, and other devices containing a radio need to be shut off during take off and landing. A lot of airlines, in Europe at least, require these device to be completely shut off, rather than just radio off. I suspect this is the case for Android Wear, too. That would create a hassle, and make Android Wear devices less interesting, for a frequent flyer.
