I met this woman the other day...
... and noticed she had a Nokia 920. Oh! I said, I had that one.
"It is a bit heavy for me, my husband got the iPhone."
"Still", I said, "This one takes better pictures and is a lot, lot tougher."
"It is tough" she said, "I got out of the car with it on my lap and someone came into the café later and said, 'Did you drop your phone outside?'".
And then a car, followed by a caravan drove over said 920.
To which I basically said, it may be heavier but at least you still have a working phone, there is no way an iPhone would have survived it, especially the iPhone 4.
Don't sent me a link to a video of a car carefully driving over an iPhone on lovely smooth tarmac because this was a well-worn road with a substantial amber and a lot of edgy stones.
