It should be clearer and definatly more scratch resistant, im not sure about the clarity yet because i havent seen any samples with special coatings on but the plain glass definatly is. the main reason for the glass is it allows me to put my gp in my pocket without a case without the ear of scratches, instead of putting it in a bulky case that i cant fit in my pocket.
Anyway some of you are getting a bit over-excited since this is purely "maarket research" to guage the market. But i can promise you more concrete details after the weekend.
