There seems little doubt that much of the Galaxy Gear's success or failure will hinge on the selection of apps that arrive on smartwatch. Samsung is making a strong push for third-party software (even in the face of limited device storage), courting a big cross section of developers at places like Path and eBay for its wearable. Popular messaging app Snapchat will also be hitting the device in the form of Snapchat Micro. As you'd expect, the app harnesses the Gear's 1.9-megapixel camera to send self-destructing images. The company's founder told Techcrunch, "Our team is constantly looking at ways to reduce the time between our experience of a moment and our ability to share it." Walking around with a camera on your wrist is certainly one way to go about it.
