Will developers flock to Will.i.am's Puls, the Apple Watch and other wrist-based wearables?

Even though apparently one over-eager fan who rushed the stage at the product unveiling is thrilled to work with music artist Wil.i.am for his Puls wearable device, Samsung Electronics, LG Electronics, Motorola Mobility and even Apple may be hard-pressed to get such an enthusiastic response to wrist-based wearables. That's especially true for developers who already have a hard enough time creating apps for smartphones and tablets that find willing customers. Whether it's traditional consumer apps or even business-oriented apps, experts say thinking "wrist-first" may take a while to become a priority for the mobile industry as a whole. Some developers think that because of app development cycles it will be two years or more before wearables become mainstream.
