How is the vibration on the Epic? The one thing I didn't like about going from the Instinct to the Hero was I can not feel the vibration of the phone. The Instinct felt like it was going to vibrate out of the holder, the Hero I could be holding it and almost not feel like it is vibrating. This is not a deal breaker, but I am always in areas that the phone needs to be on vibrate. I just hope that I will be able to feel when I actually get calls instead of calling people back after the fact because I had no clue they called.
