No case, no problem. When I see people’s iPhones severely jacked up, I always wonder what the hell they did to it. I’ve done all the usual things with my current and previous iPhones – in/out of pocket constantly, in/out of bag occasionally, skiing with it, running with it. I’ve dropped it from sitting, dropped it from standing (and I’m quite tall), dropped it while walking, on hardwood or sidewalk or road or hiking trail… The end result? No damage at all in probably 6 years of use and abuse.
I really don’t want to change the size, weight, or “friction” of the device (e.g., a rubber case would be a nightmare for getting the phone easily out of a pocket, nevermind getting it out with the “wrong” hand when you’re carrying something…)
If I do end up breaking my phone, it won’t bankrupt me to replace it. Thus, the relevant calculation is as follows:
Risk=(estimated probability of breaking phone in lifetime of phone) * (cost to replace)
I figure Risk=$30 or less, especially since the replacement cost drops considerably after a two-year contract is up. Anyway, this means you’ve got a $30 full-replacement insurance policy already in effect. Would you rather:
(a) buy a shiny new iPhone and put a nasty case around it, or
(b) buy a shiny new iPhone and pay $30 to get a no-questions-asked replacement insurance policy for the lifetime of the phone?
Option (b) is equivalent to the “no case” option, with payment deferred until the time of breakage and scaled up by 1/(probability of breakage). (So, again, this calculation only works if you won’t be sent into financial ruin by a sudden need to replace your phone, which I understand isn’t necessarily the case.)
