Unless somebody comes with a Diamond screen (hardest object on the earth) you have to live with scratch resistant ones... Diamond screen can be scratch proof
but even then another diamond can scratch it
BTW Gorilla glass 3 has been launched and it says:
[h=2]TOUGHER SCIENCE. TOUGHER PERFORMANCE.[/h] Corning? Gorilla? Glass 3 with NATIVE DAMAGE RESISTANCE™
It’s a whole new Gorilla. Tougher from the inside out with Corning’s exclusive, game-changing Native Damage Resistance, Gorilla Glass 3 offers improved scratch resistance, reduced scratch visibility, and improved retained strength. Look for new Gorilla Glass 3 coming soon on the world’s coolest smartphones, tablets and laptops.
No where it says that you cannot scratch
It just says improved scratch resistance like Apple saying improved process speed
