I appreciate the fact that this technology could make mobile devices more durable because it has less moving parts, but I don't feel going any thinner than what's currently available is desirable from an ergonomics perspective. I just don't feel as comfortable holding a phone that's 7mm thick, or less.
And I certainly don't think it's worth the risk of it folding in my pocket.
