Well I never thought I would use the SB as a camcorder. I put it on my lap, turned on video stabilization and it worked great while using my Nikon DSLR for still pics.
Are you that guy standing up and holding the tablet up in the air blocking everyone else view?
Just kidding (sort of).
A couple of years ago I made a cross country motorcycle trip. In Yellowstone, more than once, a busload of tourists would be standing by a geyser. Just as it would start to erupt, they would all hold a tablet up in the air to get photos. All I would see is a wall of tablets and some steam erupting overhead.
