I like that Apple are being so ambitious. They are literally the ONLY company that could possibly make this work as they make and control the stack from top to bottom.

That said, it's still a very tough sell. I don't think having a physical conversation with someone wearing this thing will ever really catch on, it's still taboo to this day to be looking at your phone when someone is talking to you after all.

But if the price comes down I can see this being very successful with the ever growing population of loners out there.
