I recently ordered a speck candyshell and am in love with it, except the screen protector it came with is flimsy, ugly, and distorts the screen somewhat (not to mention that the stickers taht were on it deformed it horribly). For an iPod that spends a lot of time in-pocket, are screen protectors necessary? A coworker of mine said that the screen is really hard to scratch anyways, and they aren't a big deal. If they are good to have, can anyone recommend a decent, easy-to-apply, and cheap screen protector? Thanks.
