i dont mind buying a screen protector and sticking it on, the only thing that gets to me about that is that after applying the protector onto the front of the screen will the ease of stroking the screen and using it become different or harder due to having a layer of plastic on top and not the smooth glass?
Its about as scratch resistant as you'd expect a piece of glass to be; which is to say its not very scratch resistant. I've had my phone since launch and I've already nicked the bottom (nice little chunk missing) and put minor scratches on the back. The front appears to be superior and I don't have any scratches there, but the back seems to get scratched my a strong wind.
I can't believe how this glass was advertised to be used in helicopters and how chemically strengthened it is. Be carful with you iPhone 4!
You have to remember though - on a helicopter this glass is a massive pane, and therefore can withstand a lot more pressure. A small rectangle used on something like a phone is a lot more brittle (especially being held in place by a tight steel band), and doesn't take impact as well.
that makes no logical sense to me. smaller would equal stronger, in my opinion.
