No screen protector here, for a few reasons. In no particular order:
- The glass is oliophobic (resists oils). Screen protectors have a tendency to destroy this coating
- The glass is Gorilla Glass, meaning it's strong and highly scratch resistant on its own
- I rarely keep mine in a pocket and never with anything hard/sharp, I use a belt case.
- Every screen protector I've used in the past on other phones or PDAs have caused problems with registering touch-screen actions (both resistive and capactivie touch)
I DO use a case, though. The back and sides are more scratch prone than the glass, and I do set it down on tables and desks that may scratch the back.
