Neural band is huge, glad they're shipping it already rather than waiting (years?) for a production version of Orion (the full AR glasses they demo'd a year ago together with this neural band). TheVerge found the controls great, even tried an alpha of handwriting for text input: https://youtu.be/5cVGKvl7Oek

These glasses are just "annotated reality" rather than full Augmented Reality, with just 1 small display; think Google Glass but 100x more discreet.
