Back to the smartwatch: I personally have problems with the sense/operation of ALL smartwatches (SW) they are currently out ,most of them are software related:
- Even the first wristwatch (Abraham Louis Breguet, 1810) had a decisive advantage as opposed to all modern SW: You can read the time WITHOUT pressing any button or getting the right angle for the gyro. So we need a SW where the display is ever ON (OLED or e-paper like the pebble is a big step forward)
- Bluetooth: If you use the SW as bluetooth device the range is really bad: You cannot even go to the toilet without loosing the connection (even on the expensive ones). So the big question is about getting a strong (and stable) connection without consuming too much power. (again the pebble with BT4.0 but you have to own a super new smartphone)
- Touchscreen: A really pain on small screens. Most GUI's on SW are nearly impossible to use, even the fingers of my 4-year old daughter are too big.
- Bluetooth mode: phone with the SW (loudspeaker - microphone) is lousy (if you do not just want to call a black Trans Am) . When connected to BT there is no possibility to use an additional BT-headset
