Well, except for the time I shoved it in the pocket with my keys without it's leather pouch. Poor thing got a scratch out of that. Other than that, it's been fine. I consider myself conscientous, too, but had an attack of stupid when thinking about something else.

Anti-glare screen protectors are said to help with reading in daylight, and protect from stupid stuff, so when I get a shiny new device, I'll get one.

The one that's pre-applied is not a regular screen protector; if you want a screen-protector, get a real one. That one is not very wear-resistant at all, and messes with the touch, too.
