I doubt big time it will be only for Galaxy devices. Their new watch will work with other devices. Also, I'm not sure you can really call it a monopoly. Its competition. They will be offerering an alternative to Google Glass (though its not released yet either). The fact that Samsung has such a large market share is because people are choosing them over the rest. They aren't offering their devices for free to beat out the competition. Their devices are just as expensive as the rest. Google's Nexus devices are the inexpensive ones. They just do a far worse job at marketing them. We know about them because we are here, looking at Android news usually on a daily basis (ok, I check about every hour or so, but thats my problem =D). Though I have a Note 3 (upgraded from an S3), my wife has an S4 too, I probably wouldn't buy the Samsung head gear because even on their phones I prefer Google No over S-Voice. On phones, you can choose what you want to use. On the head units, I have a feeling it'll be more locked into their own software and not what you want to choose. Because of that, if it happens, I'd choose a Google Glass device. Though to be honest, I won't be buying any of them. I don't see a need in my life for one of those.
