When you get home from the store or the postman delivers your shiny new iPod Touch 4G, do you: 1. Use it as is with no case or protection? 2. Just a screen cover (zagg, other)? 3. Full body cover (skin/zagg/other)? 4. Hard Case without screen protection? 5. Hard Case with a screen cover? Just curious if others are as over cautious as I am (#5).
