Dude, you're just ASKING to be jumped on the Metro. It looks expensive. And if it looks expensive then that means it'll be worth at least $50 at a pawn shop. You're an older gentleman and you look fairly defenseless. I'd hate to see you get punched in the face. You should do what I do and buy an actual book. Sure, you can't store thousands of them in one convenient location like you can a Kindle, but you'll also never get punched in the face for it.
Books = Not worth much in pawn shops = Not getting punched in the face.
(Living is easy if you do what I do.)
