I'm not judging in real use. I'm judging in common sense. The phone requires you to look at it to unlock.
No other iPhone requires that. Common sense tells me that will be difficult to do while driving. You don't have to look at any other iPhone to unlock it and get Siri driving instructions. On this one you will have to.
That in and of itself is a serious limitation and/or danger of the device considering how people currently use their iPhones.
If you think that people should change rather than the device, well than only fanboyism can explain that, not common sense.
