I've roamed all over Melbourne with mine, it's always in my hand bag when I go out and it's the first thing in my backpack when I head to school for my work experience.
 
I take mine everywhere I go, including construction sites, etc.

I bought it with a VISA card that doubles the manufacturer's warranty for free, so I didn't have to buy AppleCare (at least not yet).

I have insured it against accidental damage and theft (cheap!), just to be safe.

In other words, I don't leave home with out it!
