Interesting. Maybe you could do a rational economic calculation based on value lost per destructive event, frequency of events, and odds that such event will happen before a non-protected event (loss, theft, crushing which exceeds the resilience of a case). Compare that with the cost of a case and the value lost by using a case (ugliness, size).
Although I took my magpul case off my iphone 4 today (to use a tascam im2 microphone), and it's really hard to hold the glass surface, compared to the nice plastic surface of the case.
