I'm sure a lot of people are like me, we store sensitive information on our mobile devices. But my coworkers like to come to me and ask "May I borrow your iPad for a while to play?" It's very frustrating. I feel weird not lend it to them, but who knows what they will do to it. And what if they spill water on it.. aarrghh this one crazy person loves to eat and drink while browsing on my iPad. My heart is always hanging whenever he does that. So what are your thoughts? If you are thinking "No", what's a polite way to turn them down?
