You are 100% correct, and I've thought so since the day it was announced. I believe this extends to all wearables, such as watches. Apple intelligently chose to leave the camera off, which might be the most distinguishing feature, from a potential for success angle. I love the idea of both watch and glass, but would never wear glass purely due to the awkwardness it would cause to those around me. I can deal with a little nerdy. Afterall what's nerdy today can be fully acceptable in no time.
