Just yesterday my tripod hit the floor when I tied my shoe. I had it in its bag slung around my back, and it was quite tight even standing straight up, but bent over it was just too much stress for the plastic bit holding the strap. My tripod is not expensive in the first place and survived just fine, but hearing that hard *plonk* was quite a shock at first. Luckily a friend of mine had some handy extra little straps from his strap system, so I could keep on wearing it slung around my back after the incident.
My smartphone did drop onto concrete more than once but luckily survived with just some scratches in the aluminum body, even without a case.
Having not had the "pleasure" to let my camera hit the floor yet, does that mean I'm overdue?
