Watch is late, and lamely teathered to the iPhone
I don't want a watch that's dependent upon proximity to a phone. It's $350 to start with (whenever it finally arrives) and you want me to buy a phone on top of that? That Sport Watch is not going to appeal to athletes if they have to tote a phone around with them in order to get accurate mappings and measurements of runs and workouts.
If this new watch can capture heart rates and reasonably accurate mileage readings with the accelerometer alone (which I doubt), then maybe casual athletes will like it. But I can get a decked out Garmin GPS watch for much less than $350. As we learn more about battery life and wireless charging, I'm guessing this will be another thethered-to-my-phone failure. Guess what: my phone tells me what time it is and has a bigger display for maps and apps. What do I gain through the watch?
