My Beo5 has been abused by little children and some women with long nails... and has been crashing into the ground a couple of times. The screen hasn't been scratched. B&O uses some kind of special treated glass to prevent it from scratching that easy..
IF you do want to have it covered then I would also recommend Zagg's Invisible Shield (http://www.zagg.com/)

The race for quality has no finish line- so technically, it's more like a death march.
