So i've read through most of the documentation that came with my new iPod this past week, but that still leaves me with one important question. Is it ok to just leave the iPod on the dock all the time? It's all charged up, and everything is updated, but the LCD stays on with the "charged" icon. Is it ok for that to stay on the screen for long periods of time, of am i slowly killing my iPod by having that posted up there? This isn't going to eventually burn into the screen, is it? Thanks for any help!
