My daughter just bought her first ever brand new iPhone which she got on launch day. Even though she paid for it using her money from her part time job, as parents we insisted that it went straight in a decent case with a screen protector. Yes, it looks a bit less gorgeous but we know our daughter well and she can be as clumsy a person as you are ever likely to meet. She knows it too so was happy to do this.
Yesterday, on her way to school, she was running late and managed to slam it, full force, in the front door!!!
Luckily for her, the case saved it and the screen protector was the only casualty. However, she spent all day thinking she had smashed up her £700 phone and I have never seen a more relieved person when she came home and I showed her it was just the protector. Lesson learned and no harm done. She will ALWAYS be using a decent case.
