Mobile scratch-proof glass, and the road ahead

I have recently moved from a vanilla-Nokia-phone to some sort of a smart phone. My new Nokia N73 is pretty smart. One thing that constantly worries me, to the extent that I was thinking of not using this phone is the delicateness of this phone. This is a very nice phone, however the screen is so delicate, and it’s so costly that I can’t use it the way I used to use my old phone. I used to throw my old phone on my desk, on my car seat, treated it pretty badly – and it worked GREAT. However, the N73, with a 3.2 megapizels Carl Ziess lens, cannot be thrown around, with it’s delicate screen I can’t even keep my keys or coins in the same pocket I keep my phone.

I interestingly I see Judi Sohn concerned about iPhone:

there is no way I’m buying a glass-covered cell phone for $500 without accidental protection or some assurance that this thing can take everyday bumps and bruises without a problem. I want to use this thing…not display it on my wall for goodness sakes.

I also see iPhone addressing this problem by making a scratch proof glass. I wonder why Nokia doesn't make scratch proof glass? Is it because they want people to throw away their phone after a few months of usage and buy the latest models?

I am wondering what are the other major mobile innovations I am going to see in the next 12 months?
