I kinda messed up today. Without thinking I set my MBP on my Logitech Z-5500 subwoofer and left it there for a good 15 minutes or so. Both my computer and the speakers were on. I remember reading a warning on the subwoofer that said it has strong magnets in it and to not put any electronics within 2 feet of it. Are there any potential problems I might face, or am I in the clear? I feel like there's some screen distortion to the left and right, as if the image is bent, but this might be completely in my head.
