Another reason you should be get to know these devices is because big vendors like Samsung and Google are at the forefront of wearable technology. Apple is rumored to be developing the iWatch, and even Facebook recently acquired a virtual gaming company. If those guys believe in it, that likely means more innovation, at a faster pace. Of course, that doesn't necessarily mean wearable tech will be a success right off the bat, however. Samsung wearables such as the Galaxy Gear certainly have some ground to make up. Like many wearables, the Samsung Gear is tethered to a compatible device -- and it comes with a high price tag.
