I think there are two main questions to be answered:
1- Do we need to wear technology?
I guess yes, we do. The need to use technology has been so tightly woven in our everyday personal life and tasks that we need to have a peace of technology everywhere, all the time with us. Moreover, technology will probably begin to satisfy or even introduce new needs in new eras as soon as you begin to wear it.

2- Are we ready to wear it?
It all depends on the looks. This is simply one major reason why technology is approaching fashion (aside from the fact that fashion is itself a profitable market). If you need it all the time, everywhere with you, it needs to be fashionable.

So, I think it is heralding a new era. an era that you need to have it with you as part of you and using it without consciously being aware of it. The next step might be integrating technology into our bodies. Maybe a chip in our brain. it won't need to be fashionable then anymore. :)
