I'm new here (first post!) and I need some help choosing protection for my new iPod Touch I got for Christmas. My first question would be: Is it recommended to have protection? My iPod touch will be making the journey with me to school every day in the car, as well as probably lots of time in my backpack or in my pocket, but I don't plan on beating anyone upside the head with it or something. I've been looking at either the InvisibleShield, the NeoTouch/RebelTouch, or some combination of both. If you see my cellphone, you can tell that I don't care about an occasional scratch on the cover, but I'd like to keep my screen scratch free. Will the screen covers damage the screen in anyway or create a sticky mess? Do they stay on relatively well?
