There is so much potential in this kind of devices and appears that the technology is the only problem.
Key points for success:
- Display in the glass and all hardware in the frame. No protrusions and weird stuff.
- Frames in different styles and colors. As many options, better.
- Thin frame. These should not distingish from normal glass from a couple of meters.
- Battery life of 12h of use. That is, it should last a full working day.
- Usefulness and core features that actually make your day-to-day life and work better and more convenient.
- Intiutive control via phone, gestures, voice and touches on the frame.
- Integrated headphones that let you hear without having something plugged in your ears.
Basically what Google Glass had to be, but never accomplished. Hopefully the state of the technology is already there.
