My HTC hero hasn't had a screen protector since it was replaced about 4 months ago. Not a single scratch to be seen. Gotta love the new glass screens
I've had my hero since the 1st day it came out and it has not a single scratch to date. It has been through thick and thin and nothing. I am extremley impressed.
I am looking to get the Epic 4G since the Nexus S broke my heart by not having a microSD slot so I am hoping the screen lives up to the Hero's legacy.
