And yours is almost the only use case, in which a smartwatch does provide a (somewhat) better experience than a smartphone. But in most other cases it provides only equal, worse or no experience at all. Therefore potential customers will decide that the benefits do not outweigh the costs and won't buy one. Not additionally to the smartphone they already have. Bluetooth headsets also provide a better experience in the case of hands-free calling. But for most people most of the time one-handed calling is equally acceptable and headsets don't provide much benefit over this one task alone. So only very busy business people will trick themselves into believing a headset improves their productivity so much. Smartwatches won't become that giant future market big corporations like Google and Samsung are fighting over normally. If your Pebble works for you, fine. Consider yourself an early adopter, normal people won't buy what you buy.
