What are the positive aspects? I don't see any, this looks terrible to me, a waste of money for both investors and consumers
I'm limiting my points to the physical usage concerns, there are more concerns if we broaden the context, many other commenters have pointed them out. This is not even the full list of physical concerns. What people wear will have a big impact too
But why only focus on some potential shortcomings instead of appreciating the positive aspects?
Btw, there is no tech device out there for which I couldn't come up with a list of critical questions like yours.
