Ick.
This is the one feature I'm least "worried" about. But yeah, I sort of want to see how this evolves before diving into it. I don't think it's the kind of feature I'll ever use, so it's one I'm not really THAT concerned about. More of a "I'm worried about the others and, incidentally, I also want to see how this one evolves before adopting" kind of stance.
I know how the feature is supposed to work and what it purports to do and I know that there are others, triggering it in ways that make perfect sense (e.g. a phone flying forward and suddenly making impact with something). Reports of it triggering erroneously are proof of the feature doing its job. This was always going to be a feature that would require fine-tuning that you only get after sampling many more use-cases than Apple internal staff can reasonably provide. This will get better and at that point, I'll be cool with it. For now, I'm fine waiting to adopt it.
Dunno what to tell you. Sometimes my phone is in my pocket. Sometimes it isn't. Not everyone has every item they own secured in the event of a crash. Often times, I just have things on the seat of my car and 99 times out of 100, they're perfectly safe there.
Absolutely. It's the exact same scenarios and, again, it makes sense. The feature is supposed to gauge sudden impact and act accordingly. That's the entire point of it.
It's not. Most features introduced in iPhones that end up being rough around the edges to start with end up maturing after one or two releases. Not every new iPhone introduces such features. And no, not a forever wait. I don't need to spend so much money to be an early adopter to something that's only going to be smoother next go-around.
For some reason I thought you had already pulled the trigger.
Every new iPhone is the best iPhone ever!

(At least from the standpoint of having the latest features. Phones cost too much for me to not be concerned with reliability first and foremost.)
