Everyone thinks this new design is sexy but i dont get it, its very similar to the 4S which i already have. Its just taller and i wont see the back once i put it in a case.
Of course Im going to pre-order this new phone, but im not blown away by the awesome new design like i was going from the 3GS to the 4.
Is it "very similar to the 4S"? It's a different hight and thickness (taller and thinner respectively). The body is made from different materials. The band is now flush with the face and back. The camera is repositioned, as is the headphone jack. The speaker grills are redesigned, the dock connector is new and the screen is a different size and aspect ratio.
There is almost no aspect of this new iPhone that's the same as the last one aside from it being a rectangular shape with a flat back and rounded corners. The earpiece and physical buttons are in the same places but then why would you move them? They are where you ear and your fingers go! They could put all the buttons along the bottom edge and have the earpiece on the back but that would hardly make it a useful, or even usable phone!
What you are seeing as being "very similar" is merely an aspect of it being born of the same design philosophy. Look at Apple's laptops and iMacs. They share similar traits because they are built with the same DNA, so to speak. This new iPhone shares the DNA of it's predecessor and that's a good thing. It's an iPhone and will remain an iPhone.
Look at this:

It shows the evolution of the iconic Coca-Cola bottle through the years. They kept the DNA in there and updated it over time to remain fresh. That's what you do when you have iconic design. You don't toss away the most recognisable design in history - you nurture it and refine it.
In fact, if anyone wants to see how this is done brilliantly in electronics they'd need look no further than the iPod. If you were compiling a list of iconic products of the 21st Century the iPod would be damn near the top of the list. Apple managed to keep it looking fresh and exciting for a decade while retaining the classic look. An iPod is instantly recognisable as an iPod whether it's a first gen or all the way up to the most recent classics. Even the Nano without the wheel looks like an iPod but the classic design will always be that white, rectangular block with the metal back and the square screen with a simple, elegant click wheel underneath. Beautiful.

But glass shatters! Polycarbonate plastic would be best in my opinion.
Glass may shatter but plastic scratches and lacks that premium look and feel. I've owned both the 4 and 4S and have not used cases. They look almost new even today and I use my iPhone all of the time. But the plastic of the 3GS scratches far more easily.
