Do you have any kids under age 6-7?
Do you have office job where you can put the phone in your pocket?
Unfortunately for me. I got kids ages 3-5. I also have a hospital job where I am in and out of scrubs. Only place to hold the phone is either in my back scrub pocket and I may sit on it accidentally. So I put phone in my scrub pocket which is big and loose and if I am bending down to Intubate someone or doing a procedure. The phone sometimes falls out of the my pocket (even with a sticky case).
So. I can't take a case with the slippery iPhone falling out of the phone scrub shirt pocket
I have a daughter, age 7 (she'll be 8 in June) and a son who is 12.
Your rebuttal has been made on me before. I will just say that my kids have grown up around computers. Instead of smartphones both of them have always had some sort of computer to sit in front of. We (my wife and I) do not believe in allowing our children smartphones until such time as they should need them.
Both my son and daughter learned very early that touching mom's stuff is a one way ticket to swift and sudden discipline. They don't touch my stuff because it's always near me. My phone goes with me from room to room.
We did have a 3GS acting as a media device at one point. They both got equal time on it. When they were babies the phones and the computers were kept out of their reach and they were monitored when they were allowed to use them. They both started with Alphababy on a Mac - learning letters and numbers.
Since they have their own computers (an iBook G4 and a PowerBook G4) they use those. There is the occasional equal use time of my iPad Air 2, but mom's stuff is entirely off limits and there will be hell to pay if they are caught on it or with it without permission.
We have taught them respect for their property.
My son has yet to get an email address. That may happen this year. We'll see.
As for my phone, it's always in one of a few places. A business card holder on the desk in front of me at work or home or on my nightstand, in my pocket, in the compartment I have designated for it in my car, or on some surface I determine is safe to have my phone on. I wear cargo pants so my phone is always in a side pocket whenever It's in there (I don't sit on it). And since this is an expensive phone I use it with two hands - including when I pick it up or put it down.
I'm always self-aware of where my phone is. Last night some Walmart worker cut me off with her cart when I was turning.My hand was instantly over the phone in my pocket to protect it from her cart. It's just instinctive for me.
PS. I believe I had mentioned before that even though I hate cases, if I had a physical job where moving around was part of the routine I would use a case on the job. I wouldn't like it, but that's the kind of thing that can get dangerous for a phone very quickly.
