I've got a Nexus 5X, you've got questions. Let's do this!

Does it support the "OK Google" hotword detection when the phone is asleep (like the Moto X) or does it have to be on?
 
Maybe not a question specific to the 5x... Where are fingerprints saved? On the phone exclusively, on a server?

I ordered a Nexus 4 on launch day and have been using it ever since. With Lollipop, the reloads when switching apps happens quite often and is frustrating. I'm concerned with still only having 2GB of Ram in the 5X, or does Marshmallow fix the reload issue? In your opinion, will the 2GB of Ram in the Nexus 5X be sufficient with future OS updates, or could it cause issues down the road?

I'm not going to try to predict the future.
 
Is the vibrator loud or quiet? On my Nexus 5 I can have it on vibrate and not disrupt my neighbor but I can still feel it in my pocket. When I had a Nexus 6 the vibrator may as well have been a ringtone it was so loud.
 
Fair enough. I just want to make sure the 2GB is sufficient - based on what everyone is saying, it seems to be, and one can hope Google will keep this in mind for the future.
 
Some guys are saying you can get it from stores starting today...does anyone know which stores exactly? (BestBuys or what...?)
