Great question, Chris!
From a business perspective wearables add a new dimension of flexibility, another way to be connected. As mobile computing emerges, we see work merge with life and in many cases it's been a struggle to find that work/life balance. Devices today require a clunky transition (get out device, turn on, put all attention to that task until it is complete). With wearable technology, that burden is lightened by allowing you to simultaneously enjoy life and quickly transition between work and life. For example, in the morning as I'm making tea, I pop my Glass on and it tells me how long until I get to work (if I need to plan for massive traffic), basic daily stats and any important meetings I have. This allows me to go about my morning (hands free to do other routine tasks) and simultaneously prepare for the day. I can also have it read back notes from the previous day, again passively putting my mind in the right space. As the day goes on, I can take notes or real-time images quickly without opening a program or getting pen/paper, allowing me to capture moments before they are lost. Really, it opens the opportunity to keep pace in this fast world. My Glass Guide at Google was saying that some team members don't just work from home, they work from wherever they want to be. You can video conference and share what you see without having your laptop or mobile device (except for phone, you still need to be tethered). This opens up huge possibilities for business environments. From a digital marketing perspective, wearables are going to blow away the way customers interact with brands online - we will see a completely different landscape in years to come. I could go on, but I'll spare you for now!
