If you have known the serious criticism on the original Galaxy Gear, then be prepared for the surprise that Samsung is finally doing the right thing for security, battery-life saving and better performance. With Tizen on Galaxy Gear including the new Galaxy Gears, you should be able to buy one as long as your device supports it. I may recommend that you buy the new Galaxy Gear running Tizen so that your device can support it that easily. Older Samsung devices like the one I have don’t support it of course.
The only problem is that Tizen is one of the underrated OSes but putting it in the Galaxy Gears is like a good move.
