I don't believe that people will buy a computer, a smartphone, a tablet and a watch. Assuming that each of these devices remain widely used (as it is the case today) I think that people will make a choice to reach a balance.
In that scenario, it is easy to see how an expensive watch that replicates smartphone's functionalities would be a commercial failure.
Pebble on the contrary opted for having a finite, and comparatively small, set of functionalities but excel at those. Their choice of limiting the watch functionalities has two obvious positive effects:
- It keeps the price low. I want a product that will last, that I can forget about (great battery life comes into play) and that does not cost an arm. I can't afford (or don't want) to pay for both a smartwatch and a smartphone costing >200$USD. In comparison I got my Pebble for 50$USD and it's working great.
- It eliminates the redundancy that occurs between smartphones/smartwatches. Instead you have a "central nervous system": your phone and an assistant that makes interacting with that CNS easier: the watch.
I would like to see some drastic improvements in the design though. It's kind of terrible and remind the early 2000s with the ave of Palm Pilots etc... Also, it would be great to improve the sensors so I can use my Pebble as a monitor of health (and my sleep!).
I would actually spend money on a product that would monitor my sleep, bpms and wake me up in the morning at the "best" time.
