We will need some time to iterate on the form factor and user experience but it is hard to imagine a portable AR computer isn't the direction we're heading. While I truly appreciate the value of unplugging and doing things manually, it's hard to deny the utility of environmentally aware computation meshing with virtual work environments.
Arguably a true AR experience brings us MORE into the real world as the need to be rooted to a desk and cubicle is lessened and we're brought closer to product/client/stakeholder without sacrificing digital connectivity.
