What about the Rufus Cuff ??
https://www.indiegogo.com/projects/t...municator#home

Its the best concept out there, better than the iNanowatch, Galaxy Fit, Galaxy Gear, Moto 360 etc etc.

However I think its far from perfect. It should do a few modifications:
- 3 day minimum battery life on Normal-Intensive use.
- T9 Keyboard or something easier to enter input than a full qwerty.
- Shave off some of the sides and bezels, give it a smaller profile.
- Dedicated Wrist UI for the GPS/Maps App.
- Include an accurate heartbeat sensor, thermoscope and barometre.
- Trade for accurate accelarometre and gyroscrope.
- Calorie counter (to have a full-featured health accessory).
- Omit the camera (its also a hazard).
- Face speaker toward user (use for loudspeaker/alarm/notifications only)
(music would drain battery too quick - prevent such feature)
- Wireless charging (if it doesn't add bulk) otherwise a small charging implementation.

And all-in-all: make it an intuitive user interface, not slowed down by the processor and experience not ruined by a screen that lacks sunlight visibility/brightness/viewing angles/colour/refresh rate.

A 3.0 inch companion screen to always show the time, notifications, and track your daily duties (fitness, appointments, notations, weather, news, rss, twitter, stock etc) seems like a useful addition to our ever-connected lives. And $249 seems like a profitable price that doesn't ask too much.
