Is it safe to leave the iPod nano standing unsupported in a non standard dock (in my case, the mini dock) for long periods of time? I could just buy a nano dock, but I already have two iPod mini docks. I use one of the docks as a charging/alarm clock station. I have the dock plugged into some powered speakers that flank my bed, so I wake up to music that I like, not some DJ talking on the radio. As such, the iPod has to be sitting in the dock all night, or a period of about seven or eight hours. Is it safe to leave the iPod nano sitting unsupported like that? Or should I invest in a universal dock?
