I use a screen protector for my iPad. I love it because I don't have to constantly wipe the screen from the marks left by the smart pad cover. Also it keeps the coating in the screen longer. And easy to remove my daughters sticky finger prints.
I am probably going to get one for my daughter if the price is right. I think the regular iPad would be great because I have wine but I am not wanting to spend iPad 3 money on an 11 year old.
It's not an actual app. It's a setting on the phone and if anyone wants to disable it they should have to enter my iTunes password. Not acting to use a password to protect my iPad, but just might do it. I like having fast easy access to all my stuff and I have nothing that needs to be hidden.
I find it rather ridiculous that the find my iPad/iPhone feature can be turned off without having to use a password. What's the point? If anyone can turn it off it's useless. Why isn't this feature password protected?
