I used to think like you are until I had a Pebble. I don't carry my phone around the house anymore, nor do I run for it or pull it out of my pocket every time it beeps. My pebble has saved me pulling my phone out 100 times a day and going through the lock screen to see that I just wasted 10 seconds. Notifications wise it has been a game changer for me. Other functionality I'm still dubious on.
