Do You Use a Case on Your iPhone?

My wife never liked buying cases for her iPhones, she preferred the Gelaskins-style sticker with a little pattern. No biggie to me, but then one day I noticed that the sticker on the back of her iPhone 4 looked a little … bubbly. I peeled off the sticker, and with it came tons of tiny pieces of glass. She had broken the back of her iPhone and had no idea.

Me, I’m a case guy. But what about you? Do you prefer to buy a case for your iPhone, or do you like it au naturale? Let us know in the poll to the right.
