The more I'm using this phone, the more I'm liking it.
I didn't realize it had a separate Motorola camera app vs. the stock Google one (which is also on the phone). It's got a low light mode, a "brightness adjustment mode", rapid fire shots (hold down your finger on the screen and it just keeps shooting, maybe 8-9 a second?), and just seems to run that much faster than the Google one. That alone might be the thing that sells my wife on this phone.
I'm also loving being able to just wave my hand by the screen to wake it up just enough to tell me what time it is and if there's anything I need to pay attention to. Then it's just a swipe on the screen to wake it up more than that. Never realized how much I'd like it over actually hitting the power button over and over again.
Voice activation is pretty snazzy too, though it seems to get a lot of false positives. I just gave it a slightly longer wake up phrase which I hope will help in that regard - "Ahoy, phone!" seemed to be prone to just waking up for no good reason.
The only downside I see to this phone over the Nexus 5x is that you don't get the Android updates quite as fast. It looks like it's about a two month wait, Motorola are saying they expect to ship it either late November or early December. Given how well they've integrated their apps with the phone while not doing much at all to override the standard Android install makes it seem worth it to me though. I've never been a fan of bloatware, and I still don't really love that you can't uninstall the apps (though they take up very little room), they really do seem to add to things while mostly just staying out of the way. I like that within a couple of days the phone has figured out my normal sleep schedule and quiets any notifications during those hours. That's pretty cool.
$500 + tax out the door for the 64 gig model and definitely not regretting the purchase. I still get $20 off a month if I bring my own handset (does T-Mobile still do those plans? I hope so...), so comparing it to a free phone on a two year contract, it's $500 vs. $480 ($20 x 24). Easily good value for money.
