For a first gen hardware product this looks promising. Hopefully the overall UX (and particularly the resolution of the screens) lives up to the luxe / high fashion feeling you get from the website.

A big, AFAIK unstated benefit of this device is the potentially positive impact on the reader's posture. Reading-oriented tasks usually place us in a head forward posture, eventually causing musculoskeletal problems (E.G. "tech neck").

This device frees the user to take nearly any position when reading. So at minimum it avoids contributing to poor posture, but could even be worn while the user is in therapeutic positions that lengthen the spine and stretch the front muscles of the neck and core.
