I bought an IS but have not applied it yet because I think the screen is pretty scratch resistant without it (see my post about dropping on asphault without scratching) and I use iPod socks as a cases. My question is... for those of you with an IS does it reduce the amount of finger prints?? That is my only complaint and I think the only reason that I would apply my IS. The back of mine is already screwed, I put it on my laminated desk at work the 2nd day I had it and when I picked it up I slid it about and inch and there were about 1000 scratches on it already.
