Many have questioned whether we need smartwatches and asked what would the single most important feature of a smartwatch be that would cause it to be a trend like the smartphone? Since the Moto 360 came out, I'd say the answer is clearly the ability to use customisable watch faces. The kings (and queens) of smartwatches would have classic good looks ranging from sporty Casio G-Shock to classy Rolex, have a 400+ dpi full screen (multi-layered if possible), no flat tire, animations at 60+ fps, and battery power to last a day with lots of screen-on time. Sound, waterproof, ambient light sensor, health monitor, and device integration features would be lower priority. What do you think?
