A somewhay clumsy first version for games and some AR apps would be interesting but that depends on price.
I see a use for them when driving or biking. For pleasure or work, doing deliveries and having the route, gps information and recipients name. Maybe even scanning the packages so that when they open the vans door the right box pops up immediately.
Apple is invested in fitness and wellness now but glasses that fits that category is unheard of. I had glasses for 20 years before I had a lasik eye surgery done. Training with glasses suck. Today I barely use sunglasses but they serve a purpose when its sunny outside.
If the third iteration of the glasses are down to weight and size of a pair of regular pilot sunglasses and give me toggle between indoor/outdoor mode, AR view and a full day of battery they will be interesting.
