i was thinking exept for the feel it would be better in everyway like it dosent crack as easily it can be more scratch resistant? maby it could be laminated for risistance. i mean i droped my samsung galaxy s2 from my couch wich is about 30cm from the grownd it cracked it and i tap it and can tell its like maby 1.5 to 2 mm wide it makes no sense what are your thoughts and how about a phone made of bamboo sound cool? 
Iâm sure theyâve thought of it.
Plastic, while not shattering as easily, scratches more easily.
Most high-end phone screens are made of gorilla glass these days, which is pretty tough stuff.
The Screen of my htc Tattoo is made of plastic. One year in itâs already real scratchy.
Plastic screens do exist. Iâd prefer glass now.
The reason has to do with the Hardness of the material. Polymerâs by their nature are highly elastic and have a high amount of plasticity which makes them incapable of achieving the same hardness values that ceramics can reach. Iâm sure youâve heard the adage that you canât scratch a diamond. Diamond is one of the hardest materials in existence, and you canât scratch it because typically a softer material will yield to a harder one.
All plastics are generally soft materials and easy to scratch with any semi-hard material. However the Glass used in most smart phones these days is hardened to an exceptionally high value for glass which makes it scratch and wear resistant. Glass being a ceramic is capable of being hardened very well. The glass is typically harder than the metal used for your keys or other random items one keeps in their pockets. This is important for obvious reasons as it prolongs the longevity of your smart phones screen and keeps it clear for a long time.
The major downside to hardness however is brittleness, materials which are hard tend to be brittle. Phone manufacturers and their glass suppliers(Corning) have to strike a careful balance of brittleness and hardness which can be tough. The brittleness of the glass is why the screens crack so easily. There is no one super material out there unfortunately, although Gorilla Glass is quite impressive.

Were you born after 2007 ?! 
Seriously, before APPLE came along and change the rule of the game, ALL mobilephones were made with plastic screens. Its only after iPhone that every other manufacturers start using reinforced aluminum silicate glass screen.
BTW, while Gorilla glass is fairly scratch resistant, I have heard a lot of horror stories of people who dropped their iPhone 4 from their pocket and shattered/cracked their back cover and screen. So count yourself lucky at least majority of the mobile phone manufacturers still use âfilmsyâ plastic (which actually can take more beating) for the body.
Another issue is that you canât use an insulator for iOS screens. iOS relies on capacitive multi touch, and wouldnât work with an insulator. Just try taking a penny and a piece of paper and touching the screen with each over your finger and youâll see only 1 will pick up a touch at all. It somewhat limits their material choices.
Actually the glass used in todays smartphones is a enhanced glass that I wouldnât put into the same bucket as normal glass. The only thing it shares with it is that it once was silicate, but there it ends basically.
The reason against plastic is the lack of elasticity. Plastic wonât react as elastic as glass, as such the inner body would take much more damage upon a hit if you created a plastic surface as scratch resistant as gorilla glass, as every hit would hit the inner body when it bends inwards due to the lack of elasticity.
And the horror stories are true. The iPhone4 / 4S seems to put that much constraint on the glass that it canât take bumps that are âpunctualâ on the surface, they scatter the surface at worst. Know 2 people that had it happen and that it can happen on 2 sides definitely doesnât help it.
The old ones had this problem in a far lower degree as it was less glass and the rest of the body allowed it to transfer part of the energy into the body which the unibody casing of the iPhone4 design doesnât allow anymore. Its one of the few benefits of phones like the SGS2 with their âcheap plastic feelâ: if it drops to ground the energy normally gets transfered to the battery cover and the cover and battery fly out and take with them the impulse of the crash. The iphone has to take the impulse into its body and commony restrains it to the screen itself, relying on âgorilla glass being strong enough to take itâ (it normally does if the phone doesnât drop near flat on a edge or something like that).
Iâm still sure this âbreak appartâ aspect was one of the reasons behind why the best phones of all times, the Nokia 3310, was that freaking indestructable with its smart covers that would blow off whenever the pressure and impulse got too high. I had cases where even the SIM flew out due to the hit but it survived things that no phone ever since was able to even take partially
Plastics are highly elastic materials and are very good at absorbing shock.
Whal in 2007 i was 12and owned a b flip phone that cost like $30 haha you can get plastic that is conductive im prity shour but scratching would be bad maby they could make a phone where thers a slighr overhang on the screen so the casing would take the shock then put some silicone around the screen and gorrila glass and volar a perfect phone screen
Again, like I said before, Apple âchangedâ the game. Before Apple came along, ALL screens have seperate âbezelâ (LCD framing) on the LCD screen. Nowadays, everyone tries to emulate Appleâs design by having single piece glass (flushed) screen - from mobile phone to even laptops now (majority of laptops still have bezel, but latest one are starting to adopt Appleâs approach too) to Large LCD TV and Plasma TV. Bezel is now on the âoutâ of hardware fashion. Its a pity when a practical design have been forsaken for good look. But thatâs just the way it is.
Source?
Did apple change the game, or were apple simply the first to use the technology.
There is a big difference between the two.
I bought a viewsonic gtab for testing and had a similar thing happen. It hardly took a hit and dang near half the glass blew out 
They want 175 to replace the glass, thatâs about how much the windshield in my car cost me to replace. I used to take the thing everywhere, but since all it takes is a little bang to break it, I leave it in a drawer at home. It is now a non mobile device because I am too scared to move it.
Honestly, I canât remember a mobile phone before iPhone that has one piece glass construction (bezeless). If you can find one then maybe Appleâs not the first, but I am pretty certain they are.
yer apple is defently good at âborrowingâ idears and acting as if it is thers haha
Their skill is knowing what is best to borrow before everybody else. 
Not even that, itâs very easy for a third party company (or group of companies) to develop a tech, and Apple simply due to itâs size just happens to be the first to put it in a mainstream product. Doesnât mean that they pioneered the product, were the best at using the product, started integrating the product first or even had a noticeable impact in the rest of the industries desire to take it up.
And the moon could be made out of cream cheese.
Hmm, it is an interesting thought, a power proof screen maybe!!!
