What do you mean I didn't make a point? A 50% difference in strength is pretty tremendous. That's the point. The iPhone 5 to the iPhone 6 is a pretty serious downgrade, from "I can't damage it with my own strength" to "I can break it if I put a little effort into it".

If you count a 50% difference as "performs similarly" I have some dollar bills I'd like to sell you for $1.50 each.
