IMO "Solves iPhone addiction" is more or less a rephrasing of "people will quickly get bored of this".
It's just a smartphone, except you can't run third-party software, can't directly interface with it, and can't connect it to other machines. And instead of holding an N-million pixel, M-million-colour, extremely high-constrast display directly in your hand, you have to indirectly project (meaning extremely LOW contrast) a single-colour display onto your hand from a projector that's shaking around being clipped to your clothes.
The only single hypothetical upside I can see to this tech is that it might lower the two-second delay in looking at my phone caused by putting my hand in my pocket before raising my hand, but you could say that that goes against the goal of solving phone addiction.
