How scratch-proof is the ipod touch screen? I am considering buying one but it really depends on how scratch-proof the screen is. I wouldnt want to put a screen protector on the touch since you have to touch it so much and it could get annoying having a protector messing things up. But I would not be able to stand scratches on my ipod screen especially when the screen is needed so much. So my question is how scratch proof is the iPod touch screen?
