I see the value and convenience of cars (and microwaves and cloud file sharing to a certain extent).Many people didn't want to use motorised horse carriages, photon beams to cook their food or cloud services to hold their personal information where they couldn't control it....but here we are. Stranger things have happened.
I don’t see the value or convenience in a device that gives me less functionality than the devices I currently own and that’s likely to cause me discomfort and physical marks after wearing it for a short while.
There is a reason why we aren’t all wearing headsets all day and let me tell you, it isn’t because Apple hadn’t released one until a few weeks ago.
