Not only does it slide off everything, mine has broken twice after falling - once from sliding off of my wallet on a countertop, and once from me fumbling it out of my pocket.
They made me pay for the repairs ($150 each time).

Once I was climbing on some rocks, tried to send a text (yeah, I realize that was dumb), lost balance and ended up slamming the phone screen first on the rock supporting my weight with it. There is a 1/4 sandgrain width dent in the middle of the screen, barely noticeable unless you're looking for it in just the right light. As I said pretty indestructible for me.
I've not been particularly fond of LG hardware since a friend had an LG device spontaneously catch fire.
But it's fair to say that the designers had different priorities (primarily aesthetic ones - weight, thinness) which mean the device is more breakable than it could be. The iPhone is the same.
