Since nothing has been happening in Pseudoscience lately I've been trolling other fora I usually don't. I saw this and figured I'd respond even though it's over a month old now. Maybe the holidays have rendered your question moot?
Anyway, I got the Samsung Galaxy Gear 2 last year at about this time. My dog ate my old conventional watch and I figured, since it's often $100+ for a nice watch, that I may as well get one that does something other than tell time. I'm happy with the decision to get one.
I typically keep the sound and vibration off on my phone so it is nice to have the watch alert me on my wrist. Emails, text messages, facebook notifications, meeting reminders and activity notifications all buzz gently and can be read easily on the screen. I had worried that the small LCDs would be grainy but all of the watches I've seen have pretty stunning appearance. It's also a touch screen so a quick swipe or tap is all it takes to navigate through everything.
At first I tried a few different typing/texting methods but ultimately, the voice control option is the one I use most. I set the watch up to listen for voice commands when double tapped. Then I just say "Text wife, do you need me to pick up anything at the grocery store?" and it types it out for me. Same thing when I want to make a call without digging my phone out of my pocket (especially while driving), I just say "Call Plum Tomatoes" and am ordering pizza moments later.
It's also got other uses depending on the situation. The pedometer is useful but I don't walk enough. I hear the gyro sensors can be used for controlling other devices (like an RC car or something) but I haven't seen that implemented. I do use the camera fairly frequently, especially if my phone and watch happen to get separated. It's useful at work where I need to just snap a quick photo. Heart rate is interesting to check once in a while. I'm sure it would be more valuable to a more athletic person. The infrared emitter works nicely for controlling pretty much any TV or similar device. There are even apps that blast out a series of "off" signals if you wanted to be a prankster.
One really useful application I downloaded, and even paid a dollar for, let's you see through your phone's camera on your watch display. This has come in handy a few times when I've needed to see inside or behind something. For instance, I had a plumbing issue and used my phone to find a leak among some pipes in the ceiling. There is a slight lag but the images are clear and useful.
Otherwise, most of the apps aren't anything to write home about. I mean, I do have the NES emulator on it but, the screen is too small to actually use touch screen controls and see any of the action. It would be nice to see more apps that are actually useful. I haven't toyed too much with GPS companion apps but the ones I've read about seem pretty good on their face. Now that I'm typing this, I'm going to see if Ingress has finally released their smartwatch app!
All in all, my advice is that if you are thinking about a smartwatch you probably won't be disappointed by getting one and they are inexpensive enough that you won't feel too much buyer's remorse if you find it useless.
