I just had to say thank you for posting this. I love the way it looks on my phone. I have all my apps in folders, in one row across the top on four pages or so. It looks great with no icons at all but that row and the dock. Everything still seems to work fine. I don't expect it will do anything to the battery, unless you set your phone down and have the auto lock turned off. The way it pauses when you open folders and background the iPod mean the video loop isn't running when it doesn't make sense to spend the energy. Just my thought. I'll know better tomorrow when I've run it all day.
