Anyone dare to use Rain-X on their N9 screen? I use it on my car windshield and it makes it real smooth This not to make fun on this issue as I've discovered a swirly scratch at the top left hand corner (I think it came like that and I only noticed it 2 weeks after I had it) and a small vertical one more toward the centre.

This guy used it on his Samsung and says it works ... http://www.youtube.com/watch?v=kq_VTnUWbnU
