I have asked this before in various contexts but never got a good answer - why are smart watches so smart (but in return clumsy, expensive, power hungry etc)?
I don't need another smartphone I might need a companion device. It should just display a few things from my phone, e.g display navigation, notifications. My phone already has a big arm CPU and a GPS receiver, I don't want to carry another one!
It should cost peanuts and have weeks of battery.
Do these exist? If not, why? Because they can't be made? Because no one apart from me wants one?
