I know a lot of people get screen protection or anti-glare films to put on their iPad screens. The Canvas even includes it. However I've heard some people say they prefer the feeling of the glass, and it's slightly smoother to do a lot of gestures and swiping on the bare glass. So I'm looking for opinions before I decide to use one for myself. I'd hate to waste one by applying it and deciding I don't want to use it. Is the feeling THAT different? Do you personally use films for either protective or anti-glare purposes?
