Definitely a case here.
It really irks me to see some people run naked/unprotected with the iPhones, relying on & exploiting AppleCare+ for when damages occur that could have been prevented with a case. I call this abuse.
It irks me so bad because Apple has upped the price/incident probably because of people abusing it.
And there are some decent cases out there that are very slim and/or show the iPhone via see-thru plastic.
It's probably gonna get worse with these look-at-me gold iPhones out there now.
