With the arrival of post-PC era, more and more smart phones, tablets and other portable devices are on the way. Many companies nowadays are devoted to developing wearable devices, such as Google, SONY, Nike and Qualcomm. Without question, smart watches are the most popular one among these. Although there are many smart watches from different companies on the marketplace, not all of them earn customers’ favor. Launched in September 2013, Samsung Galaxy Gear smart watch is poorly reviewed by industry experts and end users. It is rumored that the Galaxy Gear had a return rate as high as 30% in the US, as a proof that many customers are not satisfied with this product. According to Ian Fogg, an analyst of IHS, he concluded: "The device exhibits multiple shortcomings, including a high price tag, a short battery life, and its limited compatibility.” Through this case, we can see that smart watch in today is still an immature product, and has a lot to go before it gets big and red.
