Missing feature for iPad!

I think iPad needs an option with protected material/apps. IPads are so nice and inviting that people often want to borrow it and try it out. It’s also usual to show sales information on iPad and the kids love to play with it. Everyone who takes your iPad in their hands get access to everything! That could be really bad.

• Imagine if a kid erase something?
• Imagine if you keep secret material on your iPad and a curious person checks it out?
• Imagine if you create personal stuff like poems, pictures or music and everyone gets access to it?

Please Apple, give us a way to protect some of the material we have on our iPads!
