Can you think of other pieces of electrical equipment that can be dropped from 3 feet as a part of their general usage?
Not general usage but I'd expect a torch to withstand the occasional knock. Dropped a 2 year old Enduro onto hard tiled floor from about 4.5 foot yesterday, small dent in the rear but still working fine. It's been knocked out the mount and thrown across the road on the commute too when I went off on black ice – again, a bit of light cosmetic damage but kept on working…
My iphone on the other hand – I can attest to the fact that they don't work when dropped from a similar height. As I had the dubious honour of being the first person in the UK to turn up at the Apple Store with a shattered screen I lucked out and got a free replacement!
