Mine boots up to the home screen 15 seconds faster than the S3. No more hitting side buttons accidentally like hitting volume when you try to use the standby button on the opposite side. Only thing I miss is the S3 using an extended battery, but I am hoping an extended battery or battery case is in the works for the G3. Man that S3 battery life was doubled with the bigger battery. Whereas others look down on an extended battery because it adds thickness and weight, I love them because it still beats the brick analog cell phones I used to carry around by a mile.
