I already own a smartphone and a 7-inch tablet for mobility. The only difference is that I can't wear my smartphone or tablet on my head. 

I am interested in the project, however, I'd never buy a gadget like that for $1.5K. That's just me. 

Agreed. I think it's an interesting project, but at the $1.5 K, it's just too expensive for my tastes. That's a lot of money to spend on a gadget that could go towards other purposes.
