I found a few spots where I like to sit my phone down at where the sound of notifications and ringers are virtually inaudible. At my desk at work I can barely hear the notifications if the phone is flat on the desk. At home if I sit the the phone backside down on the couch I hear nothing at all (even playing MP3s). I have never experienced this with my ORG Droid. Hoping once I get a cover for the phone it will elevate it enough to not miss notifications.
