I hate cases.
I have had every iPhone but one since the 3G, and only ever used a case on the 6, because it was so damn slippery. I have not used a screen protector since I left the plastic screen of the Palm Treo in the rear view mirror!
I have happily used my jet black 7 naked since launch day, and it looks fine. A few micro scratches on the back, but you have to look for them, so I don’t care.
I will be rocking my X naked as soon as it gets into my eager little hands. 🙂
I also generally skip AppleCare Plus (I have never cracked a screen or had to get service for something I did), but I’ll be getting it this time. $549 for a cracked back is too risky.
