Your uncle had a mobile, but when he needed to talk in public, he needed the kind of physical anchoring that was associated with talking on the phone in public -- enough that he generated the illusion of being on a payphone. (Much like if you talk on a cellphone that's connected to a charging chord, you still generate the illusion of a landline).
What does this say about glass? That we want it to work like things that are already there -- an always-with-you screen, for example, or a mini-GoPro -- and it might take a while to really come on its own. If it ever takes off, of course. Google has deep pockets but the acceleration is unrelenting and unforgiving.
