I have absolutely nothing to back this up, but I feel like the glass back is a emotional and subjective tactile distinction. My iPhone 5 feels cheaper than my iPhone 4. One of the biggest reasons (aside from weight), is the aluminum back. I don't know why, but it just feels cheaper. Maybe because I know glass is fragile, therefore I subconsciously place higher value on it.
