Calling Google's Project Glass "just a start," Forrester analyst Sarah Rotman Epps argues "like mobile and tablets today, in three years, wearable computing devices will matter to every product strategist."
Wearables have enormous potential for uses in health and fitness, navigation, social networking, commerce, and media. "Imagine," asks Epps, ".. video games that happen in real space. Or glasses that remind you of your colleague’s name that you really should know. Or paying for a coffee at Starbucks with your watch instead of your phone. Wearables will transform our lives in numerous ways, trivial and substantial, that we are just starting to imagine."
Wearables will "enter the mainstream by exploiting the relative strengths of the big five platforms" (Amazon, Apple, Facebook, Google, and Microsoft) says Epps in her blog post.
