At the risk of getting of topic just a bit, I'll address some stuff from a few posts above.
You can get active notification-like behavior on any phone with the app called AC Display. I use it on all my non-Maxx phones.
The G3 doesn't need rocking it to wake the display, you just double tap the screen and the phone wakes up. I find this more useful and wish the Maxx had that feature.
Long pressing the G3 volume down button wakes the phone and opens the camera pretty fast. Not much different than shake to wake the camera on the Maxx.
Maxx is still my primary phone, but for someone who doesn't have one yet, to buy one now you're getting hardware that is at least 18 months old., that is going to lock you out of some features. Real world example already for me. I bought the Moto Hint only to find that not all the features are available on the 2013 X or Droid lines.
