I have a DLO Hipcase Folio. Interestingly, the amazon link for the thing shows a picture different than what it actually looks like. It looks like THIS. Notice how the corners and sides are actually open. Right now I still have the plastic that came with the iPod touch on my device. It is serving as a sort of screen protector, but, it is now collecting a lot of dust underneath it. I am considering taking it off. Is this a good idea? The DLO Hipcase provides a screen protector, as the only time it will be open is when I'm touching it with my finger. Is there anything I should know about before I remove the plastic?
