Why is Apple so dumb as to use aluminum?

First, this is for big time Apple guys. Why on Earth would you use a aluminum case for a phone? That is stupid! Aluminum is a malleable substance and can't take much force. People say it bends and breaks and I have seen the proof and scientific evidence why. You take a flat, huge object put a malleable substance around it and say it can't bend because of glass that supposedly can't break. Wow. If you want real crystal, go to Brazil and get real crystals for $10.00. Yes that is how much some of them are. I went there and bought some so if you want proof just ask. Apple should have done this: used stainless steel or graphene for a case. Then use Gorilla glass to perfect it. Done. No bending or breaking. Graphene, I realize, is expensive to make. However, pricing a 'bendable phone' at $700 is stupider than spongebob on drugs. Just saying. That was not meant to offend anybody btw. Also using a crystal display could bring down crystal value. Saphaire crystal is not strong at all when put on a screen. It bends. The whole phone bends. I feel sorry for iPhone 6 users that don't have Apple care. Who wants to pay once a month for a $700 phone! Apple care isn't cheap either. Apple screwd up big time. Just saying.

Could I downgrade my iPhone 4s to ios 7?

If I needed to? I'm thinking about updating to ios 8.0.2 because apparently it runs better on the iPhone 4s than ios 8.0.1 does, however if it turns out it slows down my phone too much ect could I downgrade back to ios 7, or would it be difficult/not possible? Is it worth upgrading?
