I agree, it feels premium, especially the haptic button press feedback, and for texts and emails as well. For some reason the ringer vibration is comparatively lighter based on first impression.
I also don't love the lack of breathing on the moto display, even if the need is somewhat nullified by the hand waving sensor.
And the security kind of makes the moto Voice less useful as well. I love the fingerprint sensor for turning the phone on and off, but don't like having to turn the phone on to take advantage of the features of moto voice. I used to have no security on my phone to avoid this issue, but I like the fingerprint sensor. I'm not worried about security. I wish they could allow access to the fingerprint sensor for just turning the phone on and off, but without the security. Unfortunately, if you disable the security, you can't retain your fingerprints simply for the function of turning the phone on and off.
